    Correct Answer: A

    Solution :

    \[\underset{Malic\,\,acid}{\mathop{{{\operatorname{C}}_{4}}{{H}_{6}}{{O}_{5}}}}\,+3{{O}_{2}}\,\,\xrightarrow[{}]{}\,\,4C{{O}_{2}}+3{{H}_{2}}O\] \[RQ=\frac{Volume\,\,of\,\,C{{O}_{2}}}{Volume\,\,of\,\,C{{O}_{2}}}\,\,=\,\,\frac{4}{3}\] \[= \,\,1.33 \left( More than unity \right)\]
