Solution

The correct option is C $O_{2}$
RuBisco is the most abundant enzyme in nature but isn't optimized for performance like enzymes usually are. One of the chief reasons are that it has a active site that binds to both $C O_{2}$ and $O_{2}$ . But binding to $O_{2}$ leads to unnecessary reaction products that decrease the enzyme efficiency.
