a
nonstriated
b
involuntary
c
voluntary
d
striated
e

f
attached to the eyeball

Answer 1

Option A, B and F

Step-by-step explanation:

The muscle that controls the amount of light entering the eye is called the iris sphincter muscle. It is a smooth muscle, which means it is nonstriated and involuntary. This muscle is attached to the eyeball and is responsible for contracting the iris to reduce the size of the pupil, limiting the amount of light that enters the eye.
