The correct option is B Adaptation
The rod cells of eye contain a purplish pigment called visual purple, or rhodopsin. They function in dim light and at night.
Bright light splits rhodopsin and in the dark, it needs to be resynthesized.This process of resynthesis is called “dark adaptation.”
However, it takes some time for rhodopsin to be reformed. This is reason why on entering a dark room at daytime or on coming out of a well lighted room at night, we feel blind for a while.
Accommodation is the reflex mechanism by which the focus of the eye changes to make the images of distant and near objects sharp on the retina.
Mutation is a change in the genetic material (DNA) of a cell, or the change in a characteristic of an individual, which is not caused by normal genetic processes. Photoperiodism is the response of an organism to the day length.
