D Correct answer
Explanation

The mandible is the lower jawbone. Moving the mandible primarily occurs during chewing (mastication), speaking, and yawning. While dreaming and lifting weights don't require mandible movement, and playing piano uses hands/fingers, chewing food is the activity that directly involves the rhythmic opening and closing of the mandible to break down food.
