I have been asked this question in semester exam.

My enquiry is from Biosensor Variants in portion Biosensor Technology & Regulatory Issues in Biotechnology of Drug Biotechnology

Answer 1

Right option is (a) Any molecule may be protein, toxin, antigen, etc

For explanation I would say: Analyte is a molecule of protein, toxin, peptide, vitamin sugar, metal ion, etc. The sample or the analyte can be delivered as a solution. Detection or recognition is how specifically they recognize the analyte. Signal tells us a positive or negative result.
