The correct answer is: C. Deviation.
Diversion is a deviation from a straight course or from the usual or expected way of doing things. It can also mean a change in direction or purpose.
Amusement is the feeling of enjoyment or pleasure caused by something funny, entertaining, or exciting.
Distortion is the act of changing the shape or form of something, especially in a way that makes it less accurate or true.
Change is the act of making or becoming different.
In the context of the question, “Diversion” is most closely related to “Deviation”. This is because a diversion is a change in direction or purpose, while a deviation is a change from the usual or expected way of doing things. Amusement, distortion, and change are all different concepts that are not as closely related to diversion.
