Which of the following are types of immunity?

The types of immunity include active, passive, and natural, making this the correct choice.

Active immunity occurs when an organism's own immune system produces antibodies in response to an infection or vaccination. This type of immunity tends to be long-lasting because the body retains memory cells that recognize the pathogen if encountered again.

Passive immunity, on the other hand, involves the transfer of antibodies from one individual to another, such as from mother to child through breast milk or through antibody treatments. This type of immunity provides immediate protection but is temporary, as the recipient's body does not generate a lasting immune response.

Natural immunity is a more general term that often refers to immunity acquired through natural exposure to pathogens, which can lead to active immunity.

The other options include terms that do not accurately represent recognized categories of immunity. Some terms, like "temporary" and "permanent," refer to characteristics of immune responses rather than distinct types of immunity. Others like "infectious," "chronic," and "hereditary" relate to diseases and conditions rather than mechanisms of immune protection. Therefore, the first choice clearly delineates accepted types of immunity in immunology.
