A
It stays the same
B
It decreases
C
It increases
D
It becomes irregular
Explanation: 

Detailed explanation-1: -This rapid deep breathing is called hyperpnea and it’s the appropriate response to increasing carbon dioxide production in the body. Normal respiratory rate does not change significantly in adults, which means that even small changes may signify potential problems such as illness or injury.

Detailed explanation-2: -For more energy, the person needs more supply of oxygen because energy is released by the process of cellular respiration. For this more oxygen supply to the lungs, the person starts breathing rapidly.

Detailed explanation-3: -Cellular respiration is the process that the cells use to generate energy. Oxygen promotes cellular respiration no matter what we are doing; however, as the body demands more energy, the cells demand more oxygen. This demand for energy and oxygen is what causes your breathing rate to increase when you exercise.
