Explanation:

Only statement 2nd is correct.

• Defence Research & Development Organisation (DRDO), along with researchers of Indian Institute of Technology (IIT) Delhi has developed Light Weight Bullet Proof Jackets named ABHED (Advanced Ballistics for High Energy Defeat).

• ABHED (Advanced Ballistics for High Energy Defeat) is developed by DRDO and IIT Delhi.

• These jackets have been created from polymers and indigenous boron carbide ceramic material.

• The design configuration is based on the characterization of various materials at high strain rate followed by appropriate modelling and simulation.

• The new jackets are capable of mitigating the highest threat levels and are lighter than the maximum weight limits stipulated for the Army.

• It will enhance soldier protection and mobility.

Hence option 2nd is correct.
