Final answer:
The statement is true; the femur is located deep to the surrounding muscles of the thigh, such as the gluteal muscles and others that facilitate leg movement. The correct option is A.
Step-by-step explanation:
The statement that the femur is deep to the surrounding skeletal muscles is true. The femur, which is the single bone of the thigh and the longest bone in the body, is located deep within the thigh, surrounded by a variety of muscles that enable movement of the leg.
These include the anterior muscles, which extend the lower leg and the posterior muscles, which flex the lower leg. Additionally, the gluteal muscles such as the gluteus maximus, medius, and minimus are superficial to the femur and function predominantly to move the thigh bone.
Therefore, the correct option is A.
