Option 2: 3 and 4 only

Detailed Solution

Explanation:

Virtual reality (VR) and augmented reality (AR) have exciting potential in the future of gaming, marketing, e-commerce, education, and many other fields. Both technologies bring together a virtual world and the real one with enhanced, 3-D visuals. Although both seems synonymous, there are some significant differences which are as follows:

Augmented Reality (AR)	Virtual Reality (VR)	Comment
AR uses both real and virtual worlds as it overlays computer generated 3D content on the real world.	VR completely shut down the real world. It makes users think that they are in a completely virtual world.	So, statements 1 and 2 are not correct.
It is achieved by smartphones, tablets or AR wearables to enhance the real world.	It is achieved by VR headsets to generate an entirely alternate world.	So, statements 3 and 4 are correct.

Therefore, option (2) is the correct answer.
