Assertion:The primary CO2 acceptor in C4 pathway is 3-carbon molecule phosphoenol pyruvate (PEP). Reason: The enzyme responsible for this fixation is PEP carboxylase or PEPcase. (A) If both assertion and reason are true and reason is the correct explanation of assertion (B) If both assertion and reason are true but reason is not the correct explanation of assertion (C) If assertion is true but reason is false (D) If both assertion and reason are false

Primary acceptor of CO2 in C4 plants is phosphoenol pyruvic acid (PEP). Carboxylation is catalysed by enzyme PEP carboxylase (PEPCase). First stable product in C4 plant is OAA (oxaloacetic acid), a 4C compound.

Q. Assertion:The primary $C O_{2}$ acceptor in $C_{4}$ pathway is $3$ -carbon molecule phosphoenol pyruvate $(PEP)$ .
Reason : The enzyme responsible for this fixation is $PEP$ carboxylase or $PEP$ case.
