ANSWER:
A.
Explanation:
Because a full turn is a total of 360°, since there are 6 sides, each side represents 60° (360°/6).
They tell us that point C. is rotated counterclockwise 120°.
Therefore, it would be to rotate two sides in that sense counterclockwise, since 120°/60° = 2
If we look closely, the artist who meets these characteristics is A.
