Which of the following is an antigenic perennial crop?

Explanation

An antigenic perennial crop refers to a crop that is known to induce an immune response in certain individuals due to the presence of antigens or allergens. In this context, sugar beet (Beta vulgaris) is considered an antigenic perennial crop. Sugar beet is known to contain proteins that can act as allergens, leading to allergic reactions in susceptible individuals. The antigens present in sugar beet may trigger immune responses, and individuals with allergies may experience symptoms upon exposure.
