the amount of light entering the eye is regulated by the
iris
retina

Explanation:

The iris is the colored part of the eye and controls the size of the pupil, thereby regulating the amount of light entering the eye. The retina is for receiving light - not regulating light entry. The optic nerve transmits visual information to the brain, and feature detectors are neurons in the visual system that respond to specific features, not involved in regulating light entry.

Answer:

A. Iris
