B. Assertion and Reason Type Questions.
In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R).
Choose the correct option.
(a) Both Assertion (A) and Reason (R) are true and Reason (R) is a correct explanation of Assertion (A).

(b) Both Assertion (A) and Reason (R) are true but Reason (R) is not a correct explanation of
Assertion (A).
(c) Assertion (A) is true but Reason (R) is false.

(d) Assertion (A) is false but Reason (R) is true.
1. Assertion (A): The coordinate axes intersect at (0, 0).
Reason (R): The coordinates of the origin are (0, 0).
2. Assertion (A): The coordinates of a point whose x-coordinate is 3 and y-coordinate is 4 is (3, 4).
Reason (R): The corresponding point of (3, 4) in second quadrant is (–3, 4).

3. Assertion (A): The coordinates of a point whose x-coordinate is 1 and y-coordinate is 0 is (1, 0).
Reason (R): Point (1, 0) lies on x-axis on the graph.
4. Assertion (A): The coordinates of a point whose x-coordinate is 0 and y-coordinate is 1 is (1, 0).
Reason (R): Point (0, 1) lies on y-axis of the graph.
