D Correct answer
Explanation

The femur, or thigh bone, is the largest and longest bone in the human body. It extends from the hip to the knee and can withstand tremendous forces during walking and running. The stapes is the smallest bone, while 'forearm bone' and 'knee bone' are not specific enough: there are two forearm bones (radius and ulna) and the knee primarily contains the patella.
