The prompt response of "recall" that provides protection to a previously encountered antigen is an Anamnestic response.
Answer - a. Anamnestic response
The anamnestic response is a prompt response of recall which resulted in the quick appearance of antibodies in the blood with an introduction of a previously encountered antigen.
Humoral immunity deals with production of antibodies and complement proteins.
The immunological response is a response or reaction in the body to foreign particles (antigens).
