  1. A Acoelomate
  2. B Pseudocoelomate
  3. C Schizocoelomate
  4. D Spongocoelomate
Verified Solution

Answer & Solution

Correct Answer

(B) Pseudocoelomate

Step-by-step Solution

Detailed explanation

In pseudocoelomates, the body cavity is not entirely lined with mesoderm, instead, mesodermal tissue is present along the body wall but not towards the gut.
- Schizocoelomates are animals whose coelom or body cavity develops middle from a split in the mesoderm, the middle germ layer of the embryo.
- In acoelomates, coelom is absent.
Spongocoel is a central cavity found in Sponges.
