Final answer:
When you move the line of reflection, the path of light changes and consequently, the image's position of polygon ABCD also changes, due to the Law of Reflection.thus, the correct option is C).
Step-by-step explanation:
In the context of the reflection of polygon ABCD, if you move the line of reflection, the path of light changes, which in turn changes the position of the image of the polygon.
A reflection in geometry is a transformation representing a flip of a figure over a line of reflection, creating a mirror image. When the line of reflection is moved, the position of the mirrored polygon also moves accordingly.
The Law of Reflection states that the angle of incidence is equal to the angle of reflection. Therefore, in terms of optics and reflecting surfaces like mirrors, the path of reflected light adheres to this law and will vary based on the position of the reflective surface or line.
