    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 Three points A, B, C are such that AB + BC > AC, then they are collinear.
    Reason Three points are collinear if they lie on a straight line.
     

    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: D

    Solution :

    Three points A, B, C are collinear, if and onnly if AB + BC = AC but here
    \[AB+BC>AC\]
    \[\therefore\] A, B, C are not collinear.
    Hence, Assertion is false but Reason is true.
