Option B is correct.

Femur

• The femur is the upper or hind leg's bone, often known as the thighbone.
• A ligament (ligamentum teres femoris) within the socket and strong surrounding ligaments hold the head in place as it forms a ball-and-socket joint with the hip (at the acetabulum).
• The femur's neck links the shaft and head at a 125° angle in humans, which makes walking easier.
• The gluteus medius and minimus muscles are attached to the femur on the outer top of the thigh by a protrusion on the femur.
• The linea aspera, a pillar of bone, strengthens the back of the shaft, which is slightly convex forward.
• The upper part of the knee joint is formed by two enormous prominences, or condyles, on either side of the femur's lower end.
