Final answer:

The center positioned in the pons is the pontine respiratory group (PRG), comprising the apneustic and pneumotaxic centers which control the depth of inspiration and the rate of breathing respectively.

Step-by-step explanation:

The center located in the pons is the pontine respiratory group (PRG), which comes as the correct answer to your question. The PRG comprises the apneustic and pneumotaxic centers. The apneustic center contains a cluster of neuronal cell bodies that work on controlling the depth of inspiration, especially for deep breathing, by stimulating neurons in the dorsal respiratory group (DRG). Meanwhile, the pneumotaxic center is a network that inhibits the activity of neurons in the DRG to allow relaxation after inspiration, thereby controlling the overall rate of respiration.
