Solution

The correct option is B Concave lens
Near-sightedness, also known as short-sightedness or myopia, is a condition of the eye where light focuses in front of, instead of on the retina. This causes distant objects to be blurry while close objects appear normal. Hence a diverging lens or a concave lens is used to fix the problem.
