ADiaphragmatic breathing
BForced breathing effort
CQuiet resting breathing
DCostal shallow breathing
Answer & Solution
Correct answer: D. Costal shallow breathing
1. A deep breath is called diaphragmatic breathing and requires the diaphragm to contract.
2. A shallow breath is called costal breathing and requires contraction of the intercostal muscles.
3. In both cases air passively leaves the lungs as the muscle relaxes.
4. So the fourth option is correct and the first names the deep-breath pattern instead.
