Answer:
c) Rotation
Explanations:
A transformation is a way of changing the size or position of a shape.
Translation occurs when a shape is moved up, down, or sideways without changing its appearance of the shape.
For reflection, the shape is reflected through a line in order to create a mirror image of the given shape. Since the figures are not mirror images of each other hence it is not a reflection.
Rotation on the other hand turns a figure about a fixed point on the plane known as the center of rotation. A rotation can either be clockwise or counterclockwise in nature depending on the degree of rotation.
Since the given figure is turned about a fixed point on the plane, hence wee can say it illustrates a rotation.
