Which one of the-following is a medium range surface to air missile ?

Under the Integrated Guided Missile Development Programme (IGMDP), India developed five distinct missile systems. Akash is specifically classified as a medium-range surface-to-air missile (SAM),. It is a mobile system capable of engaging multiple targets like fighter jets, cruise missiles, and drones at ranges of approximately 25-35 km,. In contrast, Trishul is a short-range surface-to-air missile with a range of about 12 km, primarily designed for low-level sea-skimming targets. Prithvi is a surface-to-surface short-range ballistic missile (SRBM),, and Nag is an anti-tank guided missile (ATGM),. While the Prithvi Air Defence (PAD) variant exists for exo-atmospheric interception, the standard Prithvi family is ballistic. Therefore, Akash is the only medium-range surface-to-air missile among the given options.
