Solution

The correct option is C Changing focal length of eye lens by ciliary body
Ciliary body is a part of middle layer of eye. It consists of ciliary muscles which adjust the shape of lens. Power of accommodation is the change of focal length by eyes to focus distant or nearby objects. It is controlled due to change in lens shape by ciliary body.
