Verified step by step guidance

Understand the concept of immunity: Immunity is the body's ability to resist or eliminate potentially harmful foreign materials or abnormal cells.

Differentiate between active and passive immunity: Active immunity involves the production of antibodies by the immune system in response to the presence of antigens, while passive immunity involves the transfer of antibodies from another source.

Identify naturally acquired active immunity: This type of immunity occurs when an individual is exposed to a live pathogen, develops the disease, and then recovers, leading to the production of memory cells that provide long-term protection.

Consider the options provided: Analyze each option to determine which one involves the body's own immune response to a pathogen.

Conclude with the correct understanding: Naturally acquired active immunity is developed by recovering from an infection caused by a pathogen, as this involves the body's own immune system actively responding to and remembering the pathogen.
