Solution

The correct option is A Pons region of brain
The pneumotaxic centre, also known as the pontine respiratory group (PRG), is a network of neurons in the rostral dorsolateral pons. The PRG regulates the amount of air a person can take into the body in each breath. The absence of the PRG results in an increase in depth of respiration and a decrease in respiratory rate.
