What type of immunity is developed through exposure to infections or diseases?

The correct answer is that immunity developed through exposure to infections or diseases is known as natural immunity. This form of immunity occurs when the body is exposed to pathogens and then produces its own antibodies, resulting in a long-lasting defense against future infections from the same organism. Natural immunity can develop in various ways, such as recovering from an illness or being naturally exposed to the disease-causing pathogens in the environment.

Active immunity, which is also related to the body's response to infections, specifically refers to the production of antibodies by the immune system in response to the presence of pathogens. While similar to natural immunity, it is often distinguished by whether it results from natural exposure or vaccination.

Passive immunity, on the other hand, involves the transfer of antibodies from another source, such as from mother to child through breast milk or through immunoglobulin injections. This immunity is temporary and does not involve the individual's immune system generating a response.

Acquired immunity is a broader term that encompasses any type of immunity gained after exposure to a pathogen, including both natural and artificial (such as vaccination). However, the specific term that relates to immunity gained from direct exposure to infections or diseases is natural immunity. Hence, the correct response aligns with the definition and understanding of how the body develops immunity
