    B in front of the retina Correct Answer Incorrect Answer
    C on the retina Correct Answer Incorrect Answer
    D on the blind spot Correct Answer Incorrect Answer

    Solution

    A concave lens is used to correct short-sightedness (myopia). In myopia, images are formed in front of the retina, resulting in a blurred image. This occurs when the eye is relatively too long or the refractive powers of the cornea and lens of the eye are relatively too strong.
