The correct answer is the Defence Research and Development Organisation (DRDO).

In March 2025, the DRDO and the Indian Navy successfully conducted a flight test of the Vertical Launch Short Range Surface-to-Air Missile (VL-SRSAM) from a naval ship off the coast of Odisha.

Key Details of the VL-SRSAM:

Purpose: It is a ship-borne weapon system designed to neutralize various aerial threats at close ranges, including sea-skimming targets (missiles that fly very low to the water to avoid radar).

Design: The "Vertical Launch" capability allows the missile to be fired in any direction (360-degree coverage) without having to rotate the launcher, which is critical for quick response times during an attack.

Indigenous Development: The system was designed and developed by three DRDO laboratories based in Hyderabad, Pune, and Balasore.

Technology: It features a high-end Radio Frequency (RF) seeker for high precision and a cruciform wing configuration for enhanced maneuverability.

Why not the others?

Hindustan Aeronautics Limited (HAL): Primarily focuses on aircraft and helicopters.

Bharat Electronics Limited (BEL): While they manufacture the radars and fire control systems for such missiles, the primary development and testing partner for the missile itself is DRDO.

Bhabha Atomic Research Centre (BARC): Focuses on nuclear research and energy, not conventional missile systems.
