Answer:
Option (a).
Step-by-step explanation:
Minute respiratory volume or minute ventilation may be defined as the amount of gas exhaled or inhaled in a minute. Wright respirometer can be used to calculate the minute ventilation.
Minute ventilation can be calculated by the formula:
MRV = TV × Breaths per minute.
Here, MRV is minute respiratory volume and TV is tidal volume.
Thus, the correct answer is option (a).
