The near point of a normal human eye is approximately 25 cm.
If an object is placed closer than 25 cm, say at 5 cm, the eye cannot focus the rays properly.
As a result, the eye cannot form a clear image on the retina and the object appears blurred.
Therefore, when an object is placed at 5 cm, the human eye cannot form a clear vision.
The correct option is (D): Cannot form a clear vision
