C

Explanation:

the medial collateral, medial meniscus, and anterior cruciate

The medial collateral ligament, or tibial collateral ligament, is one of the four major ligaments of the knee. It is on the medial side of the knee joint in humans and other primates. Its primary function is to resist outward turning forces on the knee. direct blow to the knee or a noncontact injury due to cutting or sudden deceleration or stopping may damage the MCL.
