Which bone in the lower leg bears most of the body's weight?

Explanation:
In the lower leg, the main weight-bearing bone is the tibia. It carries the majority of body weight from the knee down to the ankle when you stand, walk, or run. The tibia is the thick, strong bone that bears most of the load, while the fibula runs parallel to it and mainly provides stabilization and muscle attachment, not weight-bearing to the same extent. The other options aren’t involved in carrying leg weight: the ulna is a forearm bone, the vertebrae are spinal bones, and tinnitus is a ringing in the ears, not a bone. So the tibia is the correct answer.
