Which bone is related to hand?
Explanation
Explanation
The Humerus is the long bone of the upper arm, connecting the shoulder to the elbow, making it part of the hand/arm skeleton. The Femur (thigh bone) and Tibia-Fibula (lower leg bones) belong to the leg, not the hand. So the correct answer is Humerus, option (1).
PRO TIP
Re-check your working by substituting the answer back into the original question.
