What is the body's ability to destroy and resist infection called?

• A. Immunity
• B. Tolerance
• C. Immunoglobulins
• D. Antigenicity

Answer: (A)

The main idea here is immunity—the body's defense system that protects against infection. Immunity is the ability to destroy and resist invading microbes, organs, tissues, and chemicals that could cause disease. It encompasses both immediate, nonspecific defenses like skin and white blood cells, and targeted, specific defenses such as antibodies and memory cells that recognize particular pathogens and respond more quickly if they return. This makes immunity the best answer because it describes the overall protection the body has against infection. The other terms refer to parts of the immune system or related concepts but do not describe the overall ability. Immunoglobulins are antibodies, a component of the immune response. Antigenicity is the property of a substance to provoke an immune response. Tolerance relates to the immune system's ability to avoid attacking the body's own cells or to accept certain foreign substances under specific conditions.
