Solution

The correct option is B Triploblastic and coelomate
Mollusca are triploblastic, having three primary tissue layers; endoderm, mesoderm, and ectoderm. Molluscs are coelomates but the coelom tends to be small, and the main body cavity is a hemocoel through which blood circulates.
Therefore, the correct answer is option B.
