eupnea\tnormal breathing
tachypnea\tatypical breathing pattern a
bradypnea\tatypical breathing pattern b

a atypical breathing pattern a
b atypical breathing pattern b
c atypical breathing pattern c

Explanation:

To calm down, a person typically slows their breathing rate. Bradypnea (Atypical Breathing Pattern B) is slow breathing, while Tachypnea (A) is fast and Apnea (C) is paused. Calming before a speech would involve slowing breathing, so Pattern B fits.
