Vedclass · Answer

(B) Antigens are substances that,when introduced into the body,stimulate the production of antibodies. They are mostly proteins but can also be carbohydrates,lipids,or nucleic acids. Every antigen possesses specific sites called antigenic determinants or epitopes,which allow the immune system to recognize them. The recognition ability of the immune system (specifically innate immunity) is present from birth and does not require prior exposure to the antigen. Therefore,both the Assertion and the Reason are correct,but the Reason does not explain why antigens have antigenic determinants; it describes the nature of the immune system's recognition capability. Thus,the correct option is $B$.

Assertion $(A)$: Antigen can be easily recognized because it has antigenic determinants.
Reason $(R)$: The recognition ability is innate.
