Final answer:
The ball-and-socket joint is located in the hip, where the femur's head articulates with the hip bone's socket, providing a wide range of motion.
Step-by-step explanation:
A ball-and-socket joint is found in the hip and the shoulder of the human body. These joints provide a wide range of motion, allowing for movements in multiple directions. For instance, the hip joint consists of the head of the femur (ball) fitting into the acetabulum of the hip bone (socket). This type of joint is classified as a multiaxial diarthrosis, because it allows movement around multiple axes. Accordingly, the correct answer to the question is c. hip joint.
