The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Primary acceptor of $C O_{2}$ in $C_{4}$ plants phosphoenol pyruvate acid (PEP). Carboxylation is catalysed by enzyme PEP carboxylase (PEP case). First stable product in $C_{4}$ plant is OAA (oxaloacetic acid), a 4C compound.
