Reflection across the y-axis followed by a rotation 90° clockwise about the origin is a sequence of transformations on preimage ∆ABC will NOT produce the image ∆A'B'C'.

Explanation of how reflection across axis works?

When a graph is reflected along an axis, say x-axis, then that leads the graph to go just on the opposite side of the axis as if we're seeing it in a mirror.

Thus, if you're reflecting a point (x,y) along the x-axis, then its x abscissa will stay the same but y coordinates will negate. Thus (x,y) turns to (x, -y)

Similarly, if you're reflecting a point (x,y) along the y-axis, the resultant image of the point will be (-x,y)

Answer B was not correct on Plato. reflection across the x-axis followed by a reflection across the y-axis.
