Answer:
Correct Answer: A
Solution:
Epithelial tissue forms a continuous layer over the free surface of many other tissues.
It rests on a non-cellular.
Basement membrane or Basal lamina, which separates it from the underlying connective tissue.
Since blood vessels are absent in the epithelial tissue, therefore, the materials are exchanged between the cells of epithelial tissue and vessels of connective tissue by the process of diffusion across the basement membrane.
