Answer : b
Hints & Solutions
(b) Respiratory quotient may be defined as a ratio indicating the relation of the volume of carbon dioxide given off in respiration to that of the oxygen consumed.
Respiratory Quotient (RQ) $=\frac{\text{ Amount of } CO_2 \text{ released }}{\text{ Amount of } CO_2 \text{ consumed }}$
$2(C _{51} H _{98} O_6)+145 O_2 \to 102 CO_2+98 H_2 O$
Tripalmitin+ Energy
$RQ=\frac{102 CO_2}{145 O_2}=0.7$
