The correct answer is (a) Warship.
INS Shakti is a guided missile destroyer of the Indian Navy. It is the lead ship of the Kolkata-class destroyers. The ship was built at Mazagon Dock Limited in Mumbai and was commissioned into the Indian Navy on 25 November 2014.
INS Shakti is a 6,100-ton destroyer with a length of 163 meters and a beam of 17 meters. It has a top speed of 30 knots and a range of 7,500 nautical miles. The ship is armed with a variety of weapons, including a 16-cell Barak 8 surface-to-air missile system, a 64-cell vertical launch system for Brahmos anti-ship cruise missiles, a 127 mm main gun, and two 30 mm close-in weapon systems.
INS Shakti is a highly capable warship that plays a vital role in the Indian Navy’s mission to protect India’s maritime interests.
(b) Submarine is incorrect because INS Shakti is a warship, not a submarine. Submarines are underwater vessels that are used for military purposes. They are typically armed with torpedoes and missiles, and they can travel long distances underwater.
(c) Destroyer is incorrect because INS Shakti is a warship, not a destroyer. Destroyers are warships that are smaller than aircraft carriers, but larger than frigates. They are typically armed with guns, missiles, and torpedoes, and they are used to protect aircraft carriers and other warships.
(d) Rocket launcher is incorrect because INS Shakti is a warship, not a rocket launcher. Rocket launchers are weapons that are used to launch rockets. They are typically used to fire rockets at ground targets, but they can also be used to fire rockets at aircraft.
