Question

the pupil is responsible for admitting the correct amount of light into the eyeball.
a true
b false

Explanation:

The pupil is a hole in the center of the iris. It adjusts its size to control the amount of light entering the eyeball. In bright light, the pupil constricts (becomes smaller) to reduce the light intake. In dim light, it dilates (becomes larger) to allow more light in. This is a key function of the pupil in the eye's optical system.
