Solution

The correct option is B Phosphoenol pyruvic acid carboxylase
Phosphoenol pyruvate is formed from the decarboxylation of oxloacetate and hydrolysis of one guanosine triphosphate molecule. This reaction is catalyzed by the enzyme phosphoenolpyruvate carboxylase. This reaction is a rate limiting step in gluconeogenesis.
GTP + Oxaloacetate -----> GDP + Phosphoenolpyruvate + $C O_{2}$ .
