Answer 1

Option (B).

Explanation:

From the figure attached,

Polygon ABCDE has been transformed to form an image A'B'C'D'E'

Coordinates of a point A are (-2, 2)

Coordinates of the image point A' are (2, 2).

Rule for the transformation of point A will be,

(-2, 2) → (2, 2)

(-x, y) → (x, y)

This is the rule for reflection of a point about y axis.

Therefore, line of reflection for the pre-image ABCDE will be x = 0.

Option B will be the answer.
