Solution

The correct options are
A Cellular respiration
B Pulmonary ventilation
C Breathing
Name of the process By-product
Breathing CO2
Cellular respiration CO₂+ H₂O+ 38 ATP
Pulmonary ventilation Commonly known as breathing, so as breathing the by-product is CO2
Fermentation
(takes place in anaerobic condition) Ethanol + CO₂ (alcohol fermentation)
Lactate (lactic acid fermentation).
So, the correct answer is 'Breathing', 'Cellular respiration' and 'Pulmonary ventilation'.
