Explanation:

In badminton, the rally continues until one player fails to return the shuttle (loses the point as they can't keep the rally going) or commits a fault (like a service fault, touching the net with the racket during play etc., which also results in losing the point). Jumping is a normal part of play in badminton and serving is a specific action at the start of a rally, not what ends a rally in the context of the given sentence structure.

Answer:

fails to return the shuttle, commits a fault
