Correct answer: A. Teeth
- A. Teeth
- B. Tongue
- C. Smooth muscles
- D. All of these
Explanation
Mastication means mechanical chewing, in which the teeth cut, tear and grind food. The tongue helps position food, but smooth muscles do not perform chewing; students may choose all of these because they confuse chewing with later swallowing and gut movements.
