Answer:
The correct answer would be the epithelial cells.
Explanation:
Epithelium cell forms one out of 4 basic types of animal tissue lines, along with muscle tissue, connective tissue, and nervous tissue. Epithelial cells line the outer surfaces of blood vessels and organs throughout the body.
These cell lines also present inner surfaces of cavities in many internal organs. Epithelial tissue present on a basement membrane acts as a scaffolding that assists epithelium to grow and regenerate after injuries.
Thus, the correct answer would be the epithelial cells.
