    DIRECTIONS: Following questions consist of two statements, one labelled as the ?Assertion (A)? and the other as ?Reason (R)?. You are to examine these two statements carefully and select the answer to these items using the code given below. Assertion (A): 2 is a rational number. Reason (R): The square roots of all positive integers are irrationals.

    A) Both A and R are individually true and R is the correct explanation of A:

    B) Both A and R are individually true but R is not the correct explanation of.

    C) A is true but R is false

    D) A is false but R is true.

    Correct Answer: C

    Solution :

    Here reason R is not true. \[q\ne 0\] \[\sqrt{4}=\pm 2,\] which is not an irrational number. Clearly, (A) is true.
