Correct choice is (c) glucose oxidase

For explanation: Glucose level as low as 0.15 mmol can be detected by using a glucose oxidase enzyme. The device designed for this purpose induces current flow proportional to glucose concentration. Penicillinase is used to measure penicillin concentration. Freshness of meat and fish can be detected by putrescine oxidase. Alcohol oxidase is used to detect alcohol.
