Explanation:

The Astra Mk-1 is a Beyond Visual Range (BVR), Air-to-Air Missile (AAM).

• BVR missiles are capable of engaging beyond the range of 20 nautical miles or 37 kilometers.
• AAMs are fired from an airborne asset to destroy an airborne target.
• The range for Astra Mk-1 is around 110 km.
• The missile has been designed based on requirements specified by the Indian Air Force (IAF) for BVR as well as close-combat engagement, reducing the dependency on foreign sources.
• The missile can travel at speeds more than four times that of sound and can reach a maximum altitude of 20 km, making it extremely flexible for air combat.
• Designed and developed by: Defence Research and Development Organisation (DRDO).

Hence both statements 2&3 are correct.
