Mantle in molluscs is present over which of the following regions?
Correct answer: C. Dorsal visceral body
- A. Head
- B. Dorsal muscular foot
- C. Dorsal visceral body
- D. Both A and B
Explanation
The correct option is C. The mantle in molluscs is a significant anatomical feature that forms a protective layer over the dorsal visceral body, which contains the internal organs. The mantle is often involved in secreting the shell in species that possess one. It is not associated with the head or the muscular foot, which are primarily involved in sensory functions and locomotion, respectively.
