Answer:
B. A rotation 270° clockwise
Explanation:
Transformations
It's required to find which transformation will always produce the same image as a rotation of 90° counterclockwise about the origin.
Given a point (x,y), a rotation of 90° counterclockwise will map it to the point (-y,x).
Exactly the same happens when we apply a rotation of 270° clockwise. It will map the point (x,y) to (-y,x)
Thus the correct answer is:
B. A rotation 270° clockwise
