Solution
The correct option is C Adherens junction
Tight junctions help to stop substances from leaking across a tissue. 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. Adherens junction help in cementing or packing the neighbouring cells together and are formed by a protein called Cadherin. Desmosomes are intercellular junctions that connect intermediate filaments to the cell surface and mediate strong cell-cell adhesion.
