Epithelia are tissues consisting of closely opposed cells without intervening intercellular substances. Epithelial tissue covers the whole surface of the body. It is made up of cells which are closely packed and arranged in one or more layers. This tissue is specialized to form covering or lining off all internal and external body surfaces.
Epithelial tissue is known to regenerate more rapidly when compared to other tissues. So, during injury, recovery is faster.
Thus, the correct answer is option A.
