Answer 1

Answer: (A)

Lining of coelom, which originated from mesoderm

The mesothelium is a membrane composed of simple squamous cells that form the lining of several body cavities, the pleura, peritoneum and pericardium. Mesothelial tissue also surrounds the male internal reproductive organs and covers the internal reproductive organs of women. Mesothelium that covers the internal organs is called as visceral mesothelium, while the layer that covers the body walls is called as the parietal mesothelium. Mesothelium is the epithelial component of serosa.
