Vedclass · Answer

(D) The pupil is the aperture in the center of the iris.Its size is regulated by the contraction and relaxation of the smooth muscles present in the iris.When light intensity is high,the circular muscles of the iris contract,making the pupil smaller.When light intensity is low,the radial muscles of the iris contract,making the pupil larger.Therefore,the iris controls the amount of light entering the eye by adjusting the size of the pupil.
