Solution
The correct option is A PEP carboxylase
PEP carboxylase is an enzyme found in mesophyll cells of C4 plants. It is responsible for the fixation of phosphoenol pyruvate (PEP) and CO2. PEP is the primary CO2 acceptor which is found only is C4 plants and not in C3 plants; thus, PEP carboxylase is absent in C3 plants.
