The correct option is A 0.7
The respiratory quotient (R.Q) is the ratio of CO2 produced to O2 consumed, while food is being metabolized.
RQ = CO2 eliminated / O2 consumed
In the above reaction, 102 CO2 molecules are produced and 146 O2 molecules are consumed. Therefore,
RQ = 102 / 146 = 0.7
Thus, option A is correct and other options are incorrect.
