Which is the longest bone in the human body?

Correct option is D

The correct answer is (d) Femur.

•    The femur, also known as the thigh bone, is the longest and strongest bone in the human body.
• It extends from the hip to the knee, providing structural support and enabling locomotion by bearing the weight of the body during standing, walking, and running.

Key Points:

• Length: The femur is approximately 18 inches (46 cm) in an average adult.
• Location: It connects the hip joint at the top and the knee joint at the bottom.
• Strength: The femur is designed to withstand significant forces due to its dense structure.

Additional Information:

• Tibia: Known as the shinbone, it is the second-longest bone in the body but shorter than the femur.
• Patella: The kneecap, a small triangular bone, is not long.
• Sternum: The breastbone located in the chest is not the longest bone.
