Explanation:
As you can see in the picture, they want to rotate the trapezoid by 90 degress CLOCKWISE.
This mean you have to turn it half 180 degrees. 180 degress turn means opposite site of the trapezoid. 90 decress turn means half of 180 degrees and it must turn CLOCKWISE so A would be the answer for the question.
Hope this help you :3
