(B) In $1965$,Kortschak,Hart,and Burr,while working with $^{14}CO_2$ on sugarcane leaves,found that $C_4$ dicarboxylic acids,specifically malate and aspartate,were the major labeled products during very short periods of photosynthesis.This observation was confirmed by $M$.$D$. Hatch and $C$.$R$. Slack in $1967$. The Hatch-Slack pathway,also known as the $C_4$ pathway,is an alternative mechanism for $CO_2$ fixation found in tropical and subtropical grasses and certain dicotyledons,which allows them to fix $CO_2$ with high efficiency even at low concentrations.

Tropical plants like sugarcane show high efficiency of $CO_2$ fixation because of:
