What is pronation?
A
rotation with axis of bone away from body, as when the humerus is turned outward
B
rotation with axis of bone away from body, as when the humerus is turned outward
C
rotation on axis of bone, specifically applied to the forearms, as in turning hand down by rotating radius on the ulna
D
rotation on axis of bone, specifically applied to the forearms, as in turning hand down by rotating radius on the ulna
Explanation: 

Detailed explanation-1: -Pronation is the motion that moves the forearm from the supinated (anatomical) position to the pronated (palm backward) position. This motion is produced by rotation of the radius at the proximal radioulnar joint, accompanied by movement of the radius at the distal radioulnar joint.

Detailed explanation-2: -Pronation-A rotation of the forearm that moves the palm from an anterior-facing position to a posterior-facing position, or palm facing down.

Detailed explanation-3: -The radius articulates with the ulna in a synovial pivot joint. The radial head rotates within the annular ligament and radial notch on the ulna to produce pronation of the forearm.

Detailed explanation-4: -What’s the Difference Between Supination and Pronation? Supination and pronation are terms used to describe the up or down orientation of your hand, arm, or foot. When your palm or forearm faces up, it’s supinated. When your palm or forearm faces down, it’s pronated.
