Quizplus · Accepted Answer

Immunity refers to the ability of a host organism to recognize and defend itself against the onslaught of pathogenic microorganisms. It involves the recognition of foreign substances, such as bacteria or viruses, by the immune system and activated defenses that eliminate or neutralize these substances.

Option B, passive immunity, refers to the transfer of immunity from one individual to another, such as through the transfer of antibodies from a mother to her fetus.

Option C, susceptibility, refers to the lack of immunity and increased likelihood of an individual to become infected or affected by a particular pathogen.

Option D, innate immunology, refers to the immune system's immediate, non-specific response to a pathogen, which does not require prior exposure to the pathogen.
