Option A and option C are both plausible answers, although option A is phrased to be the more likely answer, if there is only one answer to this question.
Explanation:
Compartmentalisation of enzymes can be observed in fatty acids synthesis vs fatty acid metabolism in the liver. Similarly, enzymes are often connected together in a larger protein structure to allow simultaneous control of all the enzymes such as in fatty acid synthesis in liver cells, where enzymes are all part of fatty acid synthase.
