(B) The $R.Q.$ (Respiratory Quotient) is defined as the ratio of the volume of $CO_2$ evolved to the volume of $O_2$ consumed during respiration.It depends directly on the chemical nature of the respiratory substrate being oxidized.For example,carbohydrates have an $R.Q.$ of $1.0$,while fats have an $R.Q.$ of less than $1.0$ (approx $0.7$).Therefore,the correct answer is that it depends on the substrate being oxidized.
