A)two embryos that develop in the same coelom.
B)animals that have a true coelom.
C)animals that have two coeloms.
D)animals that have no coelom.
E)animals in which the coelom disappears at gastrulation.

Accepted Answer

Coelomates are animals that have a true coelom, which is a fluid-filled body cavity completely lined by mesoderm. This coelom allows for greater flexibility and mobility in the movement of internal organs compared to acoelomates (animals with no coelom) or pseudocoelomates (animals with a partially lined body cavity). The presence of a true coelom is a defining characteristic of coelomates.
