Which of the follow missiles in ‘fire & forget’ type missile?

Nag is a third-generation anti-tank guided missile with 'fire and forget' capability, meaning once launched, it guides itself to the target without requiring the operator to continuously guide it. This is achieved through an imaging infra-red seeker that allows the missile to autonomously track and hit the target. Other options like Prithvi and Akash require guidance throughout their flight.
