Which term describes a tissue that covers surfaces both inside and outside the body?

Explanation:
Epithelial tissue forms the protective coverings that line both the outside of the body (the skin) and the inside surfaces of organs and passages (like the mouth, stomach, lungs, and blood vessels). It presents as continuous sheets of cells that act as barriers and can also specialize in absorption and secretion. The term asked for is epithelial tissue because it refers to the tissue type, not a single cell. An epithelial cell is just one cell within that tissue, while other options describe different tissue types with distinct roles (nerve tissue for signaling, fat tissue for energy storage).
