Which is the smaller of the two bones in the lower leg?

Explanation:
In the lower leg, the two long bones are the tibia and the fibula. The tibia is the larger, weight‑bearing bone that forms the shin and supports most of the body's weight. The fibula is thinner and runs alongside the tibia on the outer side; its main roles are providing muscle attachment and helping stabilize the ankle, not bearing most of the body's weight. So the smaller bone is the fibula. Radius and ulna are forearm bones, not part of the lower leg, so they don’t fit this question.
