Final answer:
The skin is the correct answer because it is an organ that consists of epithelial tissue, forming layers that protect the body.
Step-by-step explanation:
The question asks which of the following is an organ that comprises epithelial tissue. Among the options given, B. The skin is the correct answer. This is because skin is composed of epithelial cells that form layers covering the surface of the body. The outermost layer of our skin, known as the epidermis, is made of dead stratified squamous, keratinized epithelial cells. These layers help protect our body from various external factors like desiccation and pathogens. Epithelial tissue is also present as linings of cavities and lumen throughout the body, managing secretion and absorption in various organs.
