Mantle in molluscs is present over____________?
Correct answer: C. Dorsal visceral region
- A. Head
- B. Ventral muscular foot
- C. Dorsal visceral region
- D. All of these
Explanation
The molluscan mantle is a dorsal fold of the body wall that covers the visceral mass and usually forms the mantle cavity. Students may choose the muscular foot because it is another major molluscan structure, but the foot is ventral and is not covered by the mantle in the sense intended here.
