    A)  in dim light        

    B)  near objects

    C)  in bright light    

    D)  distant objects

    Correct Answer: A

    Solution :

      Iris is that part of the eye which controls the amount of light by contracting and expanding itself. In dim light, the iris contracts to expand the pupil, so as to allow more light to enter the eye. In this way, things become visible in dim light. It is given that Tina is not able to contract her iris properly. Hence, she will not be able to see properly in dim light. The correct answer is A.
