Solution
The correct option is A Gut, iris and urinary bladder
Parasympathetic nervous system (PNS) controls the involuntary action. These increases the activity of gut, iris and urinary bladder. It slows down the heart beat but increases intestinal and gland activity, and relaxes sphincter muscles in the gastrointestinal tract.
