Solution

The correct option is A Hypermetropia
As power is +2D, therefore focal length is =1P
which is +12m=+50cm so, focal length is positive which is for convex lens and a convex lens is used for correction of hypermetropia. So, the person is suffering from hypermetropia, hence correct option is A.
