Solution

The correct option is A Acoelomate
Coelom is a fluid-filled body cavity in multicellular animals surrounded by a mesodermal cell. It contains digestive tract. e.g., Annelida, Echinodermata. An animal which does not have coelom is called as acoelomate e.g., sponges, flatworms. Animals which have false coelom derived from blastocoel of the embryo are called pseudocoelomate. e.g., roundworms.
Thus, the correct answer is A.
