Answer
drum wall
Reason — When the dryer spins, the clothes move in a circular path inside the rotating drum. For circular motion, a centripetal force directed towards the centre is required which is provided by the drum wall, which pushes the clothes inward while they press against it during rotation.
Hence, the drum wall provides the necessary centripetal force that keeps the clothes moving in a circle.
