Question

Assertion: x = 3 is a line parallel to the y-axis.
Reason: Any line parallel to the y-axis is y = k, where k ∈ R.
(a) Both Assertion and Reason are true and Reason is a correct explanation of Assertion.
(b) Both Assertion and Reason are true but Reason is not a correct explanation of Assertion.
(c) Assertion is true and Reason is false.
(d) Assertion is false and Reason is true.

Answer 1

(c) Assertion is true and Reason is false.
We know that $x=3$ is a line parallel to $y$-axis.
Hence, Assertion (A) is true.
Any line parallel to the $y$-axis is of the form $x=k$, where $k\in R$.
Hence Reason (R) is not true.
Hence, Assertion (A) is true and Reason (R) is false.
