Solution
The correct option is B Fats
Respiratory quotient (RQ) is defined as the volume of carbon dioxide released to the volume of oxygen absorbed during the process of aerobic respiration. As fats are considerably much more reduced form of carbon as compared to carbohydrates and organic acids, their respiration requires much more oxygen as compared to respiration of sugars (carbohydrates) or organic acids. Thus, the value of RQ for fats is less than one.
