• B. simple squamous epithelium
• C. simple cuboidal epithelium
• D. simple columnar epithelium

Answer 1

The correct option is A transitional epithelium

Urinary bladder is lined by transitional epithelium. It is a type of stratified epithelium so this tissue consists of multiple layers of epithelial cells which can contract and expand in order to adapt to the degree of distension needed by the urinary bladder.

Simple squamous epithelium is a single layer of flat cells. This type of epithelium can be found in skin, capillary walls etc
Simple cuboidal epithelium is a type of epithelium that consists of a single layer of cube like cells. It is found in collecting ducts of the kidneys, pancreas and salivary glands.
Simple columnar epithelium consists of a single layer of columunar cells. It is found in the stomach, large intestine, rectum, fallopian tubes, etc.
