Solution

The correct option is A
(1, 2)

$x = 1$ is a straight line parallel to the y-axis and at a distance of $1$ unit from it.

Point $A (1, 2)$ is an invariant point since it lies on the line x = 1. Hence its image is the point $A (1, 2)$ itself.

What is the reflection of the point A(1,2) in the line x=1?

The correct option is A (1, 2) x=1 is a straight line parallel to the y-axis and at a distance of 1 unit from it. Point A(1,2) is an invariant point since it lies on the line x = 1. Hence its image is the point A(1,2) itself.
