    Directions: Each of these questions contains two statements: Assertion [A] and Reason [R]. Each of these questions also has four alternative choices, any one of which is the correct answer. You have to select one of the codes [a], [b], [c] and [d] given below.
    Assertion [A] HCF of (11, 17) is 1.
    Reason [R] If p and q are prime, then
    HCF (p, q) = 1
     

    A) A is true, R is true; R is a correct explanation for A.

    B) A is true, R is true; R is not a correct explanation for A.

    C) A is true; R is False.

    D) A is false; R is true.

    Correct Answer: A

    Solution :

    As both the given numbers (11,17) are prime numbers
    \[\therefore \,\,HCF\]of  \[\left( 11,\,17 \right)=1\]
     Assertion is true. Reason is true and Reason is the correct explanation of Assertion.
