Solution

The correct option is B 20 to 25 cm
The point nearest to the eye at which an object is distinctly visible is called the near point of the eye. The distance of the near point of the eye is called the least distance of distinct vision. It varies with age. For an infant, it is 5 to 8 cm, for an adult, it is 20 to 25cm.
