From the image, $Q\rightarrow R$ as operation $2$ it is a reflective image based on a horizontal line. so option $C$ is also eliminated. $\therefore$ Option $(A)$ is correct.

2 votes 2 votes If seeing this question on mobile screen, do auto-rotation off. Rotate phone clockwise wise at 90°, Figure P will become same as Figure Q. Now put mirror horizontally on top of Figure Q, reflection on mirror same as Figure R Answer: A) minimalist answered Feb 15, 2023 minimalist comment Share Follow See all 0 reply Please log in or register to add a comment.
