Solution:

Recently, the Raksha Mantri handed over three indigenously developed Defence Research and Development Organisation (DRDO) systems to Army, Navy and Air Force.
• The Indian Maritime Situational Awareness System (IMSAS) was handed over to to the Chief of Naval Staff Admiral Karambir Singh, ASTRA Mk-I Missile to Air Chief Marshal Rakesh Kumar Singh
Bhadauria and Border Surveillance System (BOSS) to the Chief of Army Staff General MM Naravane.
• Border Surveillance System (BOSS): It is an all-weather electronic surveillance system successfully designed and developed by Instruments Research & Development Establishment (IRDE), Dehradun. The
system has been deployed at the Ladakh border area for day and night surveillance. The system facilitates monitoring and surveillance by automatically detecting the intrusions in harsh highaltitude sub-zero temperature areas with remote operation capability. The system is being produced by Bharat Electronics Limited (BEL), Machlipatnam. Hence the correct answer is option (a).
• The IMSAS is a state-of-the-art, fully indigenous, a high-performance intelligent software system that provides Global Maritime Situational Picture, Marine planning tools and Analytical capabilities to Indian Navy. The system provides Maritime Operational Picture from Naval HQ to each individual ship in sea to enable Naval Command and control (C2). Centre for Artificial Intelligence & Robotics (CAIR), Bengaluru and Indian Navy has jointly conceptualised and developed the product and the BEL, Bengaluru has implemented it.
• The ASTRA Mk-I is the indigenously developed first Beyond Visual Range (BVR) Missile, which can be launched from Sukhoi-30, Light Combat Aircraft (LCA), Mig-29 and Mig-29K. Globally, very few countries have expertise and capabilities to design and produce this class of weapon system. The successful development of ASTRA weapon system by Defence Research & Development Laboratory (DRDL) Hyderabad & production by Bharat Dynamics Limited (BDL), Hyderabad is a major contribution towards ‘Atmanirbhar Bharat’.

Hence Option A is the correct choice.
