Which bone is the thinner of the two bones in the lower leg?

Explanation:
In the lower leg, the two bones are the tibia and the fibula. The thinner one is the fibula, which sits on the outside of the leg. It’s slender because its main role is to provide ankle stability and serve as an attachment point for muscles, not to bear the body's weight. The tibia, by contrast, is thicker and acts as the primary weight-bearing bone. The other options are arm bones (radius and ulna) and aren’t part of the lower leg.
