Which is the thigh bone?

• A. Tibia
• B. Fibula
• C. Pelvis
• D. Femur

Answer: (D)

The thigh bone is the femur, a long bone that runs from the hip to the knee. It is the longest and strongest bone in the body, bearing and transmitting most of the body's weight during movement. The proximal end has a rounded head that fits into the hip socket to form the hip joint, while the distal end helps form the knee joint with the tibia. The other options are not the thigh bone: the tibia is the shin bone in the lower leg, the fibula is a thinner bone beside the tibia, and the pelvis refers to the hip region, not a single thigh bone.
