What is the opposite force of Lift?

Explanation:
Lift is the upward aerodynamic force produced by the wings as air flows over them. Its opposite is weight, the downward pull of gravity on the aircraft. In level flight, these two forces balance, with lift matching weight so the plane stays at a constant altitude. If weight exceeds lift, the aircraft descends; if lift exceeds weight, it climbs. The other choices aren’t the direct vertical opposite: drag acts horizontally against motion, thrust pushes forward, and altitude is a measure, not a force.
