    A)  Abscisic acid

    B)  Indole butyric acid

    C)  Indole-3-acetic acid

    D)  Gibberellic acid

    Correct Answer: A

    Solution :

     Abscisic acid (ABA), also known as abscise II and dorrnin, is a plant hormone. It functions in many plant developmental processes, including bud dormancy. Abscisic acid is a derivative ofm carotenoids. It was called "absicisin II" originally because it was thought to play a major role in abscission of fruits. At about the same time another group was calling it "dormin" because they thought it had a major role in bud dormancy. The name abscisic acid (ABA) was coined by a compromise between the two groups.
