Solution

The correct option is B 0.7
RQ value is greater than one in aerobic conditions when the organic acids get to break down as a respiratory substrate. Ex: Oxalic acid - 4, carbohydrate - 1. RQ value is less than one in aerobic conditions when the respiratory substrates are proteins or fats. Ex: tripalmitin (C $_{5}$ $_{1}$ H $_{9}$ $_{8}$ O $_{6}$ )- 0.7.
So the correct option is '0.7'.
