The given question is incomplete the complete question is:

In mammals and some reptiles, the coelom is divided into smaller cavities that enclose the lungs, heart, and gut. What are these cavities called?

A. pleural, pericardial, and peritoneal cavities

B. thoracic, pleural, and pericardial cavities

C. pleural, pericardial, and cardial cavities

D. perithoracic, peritoneal, and pericardial cavities

Answer: Option A

Explanation:

The intra embryonic coelomic cavity forms within the cavity of the lateral plate in the early development (week 3 or 4). This space undergoes a huge morphological change. It does into changes by folding or partitioning when there is a development of the 3 major cavities in the body.

These cavities are known as pleural, pericardial and peritoneal cavities. The single appearing cavity divides the lateral plate into the splanchnic and somatic mesoderm.

Then the later will be divided into the cavities.
