The iris, which regulates the size of the pupil, is made up of unconscious smooth muscles. This is crucial for the eyes' ability to adjust to various light levels.

 

Cardiac muscles, which are unconscious muscles that aid in blood pumping, make up the structure of the heart. The striated muscles that make up the biceps on the upper arm are controllable by the individual. The smooth muscle fibers that make up the abdominal wall support the peristaltic movement, which happens uncontrollably.

 

So the correct answer is “Iris - Involuntary smooth muscle”.
