Solution
The correct option is C A-iii, B-i, C-iv, D-ii
Tight junctions are cell junctions located at the apical surface of the adjacent epithelial cells. They prevent substances from leaking across the surrounding tissues.
Adhering junctions cement the neighbouring cells to keep them intact.
Gap junctions facilitate the cells to communicate with each other for the transfer of ions and molecules.
Basement membrane are extracellular matrix on which the epithelial cells rest and are connected to the connective tissue present beneath.
