A) They support the entire body.
B) They protect soft body parts.
C) They produce blood cells.

Accepted Answer

The function of the skeletal system that requires the leg bones to be extremely strong is supporting the entire body.

Therefore, the leg bones need to be strong enough to handle this weight-bearing function.
