Mirror is related to Reflection in the same way as Water is related to Refraction.

Explanation:
Mirror and Water are both related to different phenomena of light. Let's discuss each of them in detail.

Mirror and Reflection:
A mirror is a smooth and shiny surface that reflects light in a predictable manner. When light rays fall on a mirror, they bounce back or reflect off the mirror's surface. This phenomenon is called reflection. The angle at which the light rays bounce off the mirror is equal to the angle at which they strike the mirror. Mirrors are commonly used to see our own reflection or to reflect light in a specific direction.

Water and Refraction:
Water, on the other hand, is related to the phenomenon of refraction. Refraction occurs when light passes through a medium, such as water, and changes direction due to a change in its speed. When light travels from one medium to another, like from air to water, it slows down and bends. This bending of light is called refraction. It happens because light travels at different speeds in different mediums.

Relation between Mirror and Reflection, and Water and Refraction:
The relation between Mirror and Reflection, and Water and Refraction lies in the fact that both mirrors and water interact with light and cause it to change its path. While mirrors reflect light, water refracts it.

In the given analogy, Mirror is related to Reflection. Similarly, Water is related to Refraction. Reflection and Refraction are two different phenomena of light. Reflection refers to the bouncing back of light rays from a surface, while Refraction refers to the bending of light as it passes from one medium to another.

Therefore, the correct answer is option D) Refraction.
