Solution

The correct option is D Zero.
During aerobic respiration, O $_{2}$ is consumed and CO $_{2}$ is released. The ratio of the volume of CO $_{2}$ evolved to the volume of O $_{2}$ consumed in respiration is called as the respiratory quotient (RQ) or respiratory ratio. Thus, the following expression is used to calculate the value of RQ.
RQ = volume of CO $_{2}$ evolved/ volume of O $_{2}$ consumed.
In an actively photosynthesizing tissue, the net volume of carbon dioxide evolved (i.e., volume of carbon dioxide produced in respiration minus that utilised in photosynthesis) is equal to net volume of oxygen (i.e., volume of oxygen consumed in respiration minus that evolved in photosynthesis).

As if we take from 0 to infinity it is positive

And if also take from 1to infinity it is positive

So has zero any value
