Answer: The Pupil is the black part present in the human eye.
Explanation:
Pupil is the black ball that is bounded by the muscles of Iris which helps in the contraction and relaxation of the Pupil. The Iris controls the amount of rays of light passing through it to the Retina (a dark hollow chamber where the images are made). If too much bright light rays is entering in our eyes, the iris shortens or contracts. If dim light rays are entering in our eyes, the iris widens or relaxes.
Hope this clears your doubt. Thanks!
