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 into a lipoprotein scotopsin and a carotenoid pigment retinene. The splitting of rhodopsin depolarizes the rod cell. In the dark, rhodopsin is resynthesized from scotopsin and retinene
This process is called “dark adaptation.” It makes the rods functional. It takes some time for rhodopsin to be reformed. This is 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. When we go from darkness into bright light, we feel difficulty in seeing properly for a moment till rhodopsin is bleached and cones become functional.
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
