Which joint is located between the radius and ulna closer to the elbow?

Explanation:
Forearm anatomy: the radius and ulna connect at two radioulnar joints. The proximal radioulnar joint is the one closest to the elbow, where the radial head interacts with the ulna. This is the joint that lies nearer the elbow, enabling forearm rotation (pronation and supination). The other options are ligaments located in other parts of the body—patellotibial in the knee, pubofemoral in the hip, and plantar calcaneonavicular in the foot—so they do not connect the radius and ulna.
