    A) If both the assertion and the reason are true and the reason is a correct explanation of the assertion

    B) If both the assertion and reason are true but the reason is not a correct explanation of the assertion 

    C) If the assertion is true but the reason is false

    D) If both the assertion and reason are false

    E) If the assertion is false but reason is true

    Correct Answer: E

    Solution :

    In spiral arrangement, each node bears a leaf and the leaves of the adjacent nodes roughly lie towards the opposite sides. In opposite arrangement, two leaves are borne on the opposite sides of a single node. When three or more leaves develop on the nodes, they form whorled arrangement.
