Answer: (a)

Simple squamous epithelium is composed of large flat cells whose edges fit closely together like the tiles on a floor, hence it is also called pavement epithelium. The nuclei of the cells are flattened and often lie at the centre of the cells causing bulgings of the cell's surface. The epithelium lines the blood vessels, lymph vessels, heart, terminal bronchioles, alveoli of the lungs, walls of the Bowman's capsules, and descending limbs of the loop of Henle. In the blood vessels and heart, it is called endothelium.
