Solution

The correct option is D $(4, 5), (- 2, 2)$
Reflection of (4, 1) in y = 3 will be (4, 5) as the x- coordinate will not change but the y - coordinate shifts 4 units upwards such that y = 3 acts as a mirror.
Reflection of (-2, 4) in y = 3 will be (-2, 2) as the x- coordinate will not change but the y - coordinate shifts 2 units downwards such that y = 3 acts as a mirror.
