    The correct option is: b. Tight junctions

    Explanation:

    Tight junctions is a type of cell junction that are found in the epithelia of vertebrates. They are composed of branching network of the sealing strands.

    They seal the paracellular pathway and prevents leakage and regulates the transportation of solute and water between the epithelial layers. It is also responsible for the formation of leaky pathways for water or small ions.
