Options
- AA-I, B-II, C-III
- BA-II, B-III, C-I
- CA-II, B-I, C-IV
- DA-II, B-I, C-III
Correct answer
D. A-II, B-I, C-III
Step-by-step solution
According to NCERT, cell junctions serve specific structural and functional roles in animal tissues: Tight junctions help to stop substances from leaking across a tissue. (A matches II) Adhering junctions perform cementing to keep neighbouring cells together. (B matches I) Gap junctions facilitate the cells to communicate with each other by connecting the cytoplasm of adjoining cells, for rapid transfer of ions, small molecules and sometimes big molecules. (C matches III) Option 1 incorrectly swaps the functions of
