A) unity
B) infinity
C) >1
D) zero
Correct Answer: D
Solution :
At compensation point, the rate of photosynthesis is equal to rate of respiration and there is no gaseous exchange .i.e., volume of \[{{O}_{2}}\] absorbed and volume of \[C{{O}_{2}}\] evolved both are zero. \[\begin{align} & \therefore \,\text{Respiratory Quotient }\left( \text{RQ} \right) \\ & =\,\frac{\text{Volume of C}{{\text{O}}_{2}}}{\text{Volume of}\,{{O}_{2}}} \\ & =\,\frac{0}{0}=\,0 \\ \end{align}\]
