Option 4: 1 and 3 only

Detailed Solution

Explanation:

  • The Chief of Defence Staff (CDS) serves as the Permanent Chairman of the Chiefs of Staff Committee (COSC), which includes the three Service Chiefs (Army, Navy, Air Force). So, statement 1 is correct.

  • The CDS does not exercise military command over the three Service Chiefs. Each Service Chief retains operational command over their respective service. So, statement 2 is not correct.

  • The CDS acts as the Principal Military Advisor to the Defence Minister on all tri-service matters. So, statement 3 is correct. 

Therefore, option (4) is the correct answer.
