Which term describes rotation of the forearm so the palm faces downward?

Explanation:
Pronation is the forearm rotation that makes the palm face downward. In this motion, the radius rotates over the ulna so the distal end of the radius crosses over the ulna, effectively turning the hand so the palm points downward (or posteriorly relative to the anatomical position). The muscles mainly responsible are the pronator teres and pronator quadratus. The opposite movement, supination, turns the palm upward. Inversion and eversion are movements of the foot, not the forearm, so they don’t describe this action.
