Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Secondary metabolites have identifiable functions and play known roles in normal physiological processes of the producer organism. Reason (R): Abrin and ricin are secondary metabolites classified under toxins. In the light of the above statements, choose the most appropriate answer from the options

Step-by-step solution

Assertion (A) is not correct because primary metabolites have identifiable functions and play known roles in normal physiological processes. The exact roles or functions of many secondary metabolites in the host organisms are not fully understood, though many are useful to human welfare or have ecological importance. Reason (R) is correct because abrin and ricin are indeed classified as toxins under secondary metabolites. Therefore, Assertion (A) is not correct but Reason (R) is correct. Answer: Assertion (A) is no
