    A) Radish, turnip and carrot are modifications of X.

    B) X is found in gram while Y is found in barley.

    C) X spreads horizontally hence cannot provide strong anchorage whereas Y penetrates very deep into the soil hence provides strong anchorage.

    D) In Y, primary root is short-lived while X has persistent primary root.

    Correct Answer: C

    Solution :

    In the given paragraph, X and Y refer to tap roots and fibrous roots respectively. Tap roots (X) penetrate very deep into the soil hence provide strong anchorage to the plant whereas fibrous roots (Y) are shallow and grow horizontally in the soil hence they cannot provide very strong anchorage to the plant.
