Right answer is (a) signal processor

Best explanation: In a biosensor, signal processor is one that involves subtracting a ‘reference’ baseline signal from the sample signal. Transducer is one that converts the reaction data into an electrical signal. Amplifier is used to amplify the signal from the transducer as it is of low frequency. Detector is used to detect the value obtained from the whole process.
