Afracture of which bone would cause difficulty with chewing? a. sacrum b. humerus c. mandible d. metacarpal

The correct answer is C. Mandible.

Explanation

The jaw is a set of bones in the head that serve as a support for the teeth, and form the mouth. This consists of a lower jaw or mandible that is movable and upper jaw that is fixed in place. These bones support the mouth, and therefore they are both important for actions such as talking or chewing, that is why a fracture or injury in this part can cause discomfort or prevent us from performing such activities. So, the correct answer is C. Mandible
