Correct Answer: Option A) 1 only
Statement 1 is Correct: Trishul was indeed developed under India's Integrated Guided Missile Development Programme (IGMDP). The IGMDP was initiated in 1983 under the leadership of Dr. APJ Abdul Kalam, and Trishul was one of the five missile systems developed under this program, along with Agni, Prithvi, Akash, and Nag.
Statement 2 is Incorrect: The Maitri missile project was a joint venture between India and France, but it was not eventually developed and inducted by DRDO. The project faced delays and was later shelved. India later opted for other missile systems for its defense needs.
Statement 3 is Incorrect: The Trishul missile was primarily designed as a short-range surface-to-air missile (SAM) for the Indian Army, Navy, and Air Force. It did not have anti-tank or air-to-air variants as claimed. Trishul was specifically developed as a quick-reaction missile to counter low-flying aircraft and cruise missiles.
