The correct answer is that joints minimize frictional force between bones. Joints act as the connection points between bones and facilitate movement by allowing for various ranges of motion. They are designed with cartilage that covers the ends of the bones, which serves as a smooth layer that reduces friction when bones move against each other. Additionally, synovial fluid within the joints lubricates the surfaces, enhancing their ability to move freely without excessive wear or damage.

Tendons, ligaments, and muscles each play important roles in the muscular-skeletal system, but their primary functions do not directly relate to minimizing the friction between bones during movement. Tendons connect muscles to bones and assist in movement, while ligaments connect bones to one another, providing stability to joints. Muscles are responsible for generating the force needed for movement, but they do not contribute to reducing friction at the bone surfaces themselves.
