Step 1: Understanding the Structure of Indian Security Forces:
India's security forces are broadly divided into the Armed Forces and the Central Armed Police Forces (CAPFs). It is essential to know which ministry controls which force.
Step 2: Categorizing the Forces:
Indian Army, Indian Navy, Indian Air Force: These three constitute the Indian Armed Forces. Their primary role is to defend the nation against external aggression. They operate directly under the command and control of the Ministry of Defence. So, (A), (B), and (C) are correct.
CRPF (Central Reserve Police Force) and BSF (Border Security Force): These are part of the Central Armed Police Forces (CAPFs). Their roles include internal security, border guarding, and assisting law and order. The CAPFs (which also include CISF, ITBP, and SSB) operate under the administrative control of the Ministry of Home Affairs, not the Ministry of Defence. So, (D) and (E) are incorrect.
Step 3: Forming the Correct Combination:
The forces that come under the Ministry of Defence are the Indian Army, Indian Navy, and Indian Air Force. This corresponds to (A), (B), and (C).
Step 4: Final Answer:
The correct option is (B).
