Step-by-step explanation:

Answer 2

Answer: Choice A   $R_0, 90^{\circ}$

The R stands for "rotation". The "O" as a small subscript means "origin" which is where the x and y axis cross. The 90 degrees means we rotate 90 degrees counterclockwise. This is equivalent to 270 degrees clockwise, but writing $R_0, 270^{\circ}$ is not correct as we don't rotate 270 degrees counterclockwise.
