    Answer is A. Vicariance does not require organisms to disperse.

    Explanation:

    Vicariance occurs when there is a sudden occurrence barrier, such as geographical area barrier that cause the isolation of species of organisms.

    Dispersal involves the movement of the organism while vicariance is the change in environment due to sudden occurrence in the area.

    In this case, vicariance does not involve movement of organisms while dispersal involves movement of organisms.
