Answer & solution

Answer: (c) Bhargavastra

Correct Answer: Bhargavastra — Option (c)
India successfully tested the Bhargavastra micro-missile/rocket system in 2025. Key facts about Bhargavastra : Bhargavastra is an indigenous anti-drone micro-missile/short-range rocket system developed by Economic Explosives Limited (EEL) under the Ministry of Defence ; It is designed primarily as a counter-drone/counter-UAV (Unmanned Aerial Vehicle) weapon system — to shoot down enemy drones and aerial threats; The system can fire multiple micro-rockets/missiles in rapid succession, creating a 'wall' of projectiles to intercept drone swarms; It is a cost-effective solution against the emerging threat of drone swarms in modern warfare; The successful trials of Bhargavastra in 2025 demonstrated India's growing capability in counter-drone technology; The system can be mounted on vehicles, making it mobile and tactically versatile; ' Bhargavastra ' is named after the powerful weapon (astra) of the sage Bhrigu (Bhargava) in Hindu mythology.
Option (a) Astra-II — Incorrect: Astra-II is an air-to-air beyond-visual-range (BVR) missile developed by DRDO for the Indian Air Force; while it is an advanced missile system, Astra-II is not a micro-missile/counter-drone system and is different from the Bhargavastra tested in 2025.
