Answer: c

Explanation:

The Assam government recently completed an eviction drive to clear alleged encroachment from around 6,200 bighas (nearly 830 hectares) of land in Burhachapori Wildlife Sanctuary, affecting 710 families.

About Bigha:

It is a traditional unit of land measurement commonly used in India, Bangladesh, and Nepal.

It is generally used for the measurement of agricultural land, although it may also be used for residential plots.

Historical Context:

The origins of Bigha trace back to ancient South Asian practices.

It originated from the Sanskrit term ‘vigraha,’ which translates to division.

Before the introduction of modern units like the acre or hectare, landowners and farmers relied on Bigha to calculate land for cultivation, taxation, and trade.

Over time, it became deeply rooted in the cultural and economic fabric of these regions.

Popular in states where farming is common, Bigha is used by farmers when measuring plots and negotiating land prices.

This unit is most commonly used in the following Indian states: Assam, Bihar, Gujarat, Haryana, Himachal Pradesh, Jharkhand, Madhya Pradesh, Punjab, Rajasthan, Uttarakhand, Uttar Pradesh, and West Bengal.

The exact measurement of bigha differs from state to state.

For instance, in West Bengal and Assam, one bigha equals about 14,400 sq.ft., while in Punjab, it measures approximately 9,070 sq.ft.

There is no national standard for the size of a bigha, and it is typically smaller than an acre, which is 43,560 sq.ft. or 4,047 sq.m.

Bigha has several subunits in different places; some common ones are:

Katha

Biswa

Nalli

Bigha in Bangladesh and Nepal:

Bangladesh: Standardized under British rule at 14,400 sq.ft (1,340 sq.m.).

Nepal: A bigha equals about 6,772.63 sq.m., with local variations.

Hence option c is the correct answer.

Answer: a

Explanation:

ISRO’s PSLV-C62 rocket is set to lift off from the first launchpad at Sriharikota, marking India’s first space launch of 2026.

About PSLV-C62 Mission:

It is a multi-payload mission of the Indian Space Research Organisation (ISRO) that will carry one primary satellite and 18 secondary payloads into space.

It is ISRO’s first space launch of 2026.

It is scheduled to lift off from Sriharikota.

The mission’s primary payload is the earth observation satellite EOS-N1 (codenamed ‘Anvesha’), an hyperspectral imaging satellite developed primarily for the Defence Research and Development Organisation (DRDO) for strategic purposes.

Unlike conventional imaging satellites, hyperspectral satellites can “see” the Earth in hundreds of wavelengths, allowing them to identify materials and objects with far greater precision.

This capability makes EOS-N1 a high-value asset for national security, border surveillance and strategic monitoring.

At the same time, the satellite will also be used for civilian applications such as agriculture planning, urban mapping, mineral detection, and environmental monitoring.

PSLV-C62 will also carry Europe’s Kestrel Initial Demonstrator (KID), an experimental mission involving a small re-entry capsule developed in collaboration with a Spanish startup.

The capsule is expected to re-enter Earth’s atmosphere and splash down in the South Pacific Ocean.

Additionally, 17 commercial payloads from startups and research institutions across India, Mauritius, Luxembourg, the UAE, Singapore, Europe, and the United States are manifested for the PSLV-C62 Mission.

Several Indian startups and academic institutions are also flying their satellites.

These include OrbitAID Aerospace’s AayulSAT, CV Raman Global University’s CGUSAT-1, Dhruva Space’s DA-1, Space Kidz India’s SR-2, Assam Don Bosco University’s Lachit-1, Akshath Aerospace’s Solaras-S4, and Dayanand Sagar University’s DSAT-1.

Bengaluru-based OrbitAID Aerospace’s AayulSAT stands out as a historic first.

It is India’s maiden on-orbit satellite refuelling payload.

The mission aims to demonstrate technologies that could extend the operational life of satellites by enabling in-orbit servicing and refuelling.

Such capabilities are seen as crucial for tackling space debris and improving sustainability in Earth’s increasingly crowded orbital environment.

Hence only statement 1 is correct.
