When an antigen attacks the body, it activates adaptive immunity. This adaptive immunity produces a strong response when it encounters the same antigen for the second time. Which feature of adaptive immunity is essential for this kind of response?

A) the ability to remember the antigen it encounters

Adaptative immunity reacts in a more general way producing nonspecific antibodies against the foreign antigen when the organism is first attacked by that foreign antigen. The second time around, when the organism is faced again with the same foreign antigen, it produces a much stronger response because it memorised the antigen and is not strange anymore so the response can be more specific, quicker, and effective.
