    Read the assertion and reason carefully:
    Assertion            :     Whole compound leaf of Clematis converts into tendril.
    Reason              :     Gloriosa superba shows whole leaf tendril.

    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: C

    Solution :

    The petiole, rachis and the stalks of the leaflets in Clematis are sensitive to contact and can coil around the support to help the plant in climbing. In whole leaf tendril, the whole leaf is modified into a tendril for climbing. The leaf apices of Gloriosa superba are greatly elongated to function like the tendrils.
