An example of adaptive or specific immunity is:

The correct answer represents an example of adaptive or specific immunity because a cell-mediated response involves the activation of T lymphocytes, which play a crucial role in recognizing and responding to specific antigens. This form of immunity is highly specific, meaning it tailors its response to particular pathogens or infected cells, unlike the innate immune responses that are more generalized.

Cell-mediated immunity is essential for combating intracellular pathogens, such as viruses and some bacteria, where the immune system must identify and destroy infected cells. This is a hallmark of adaptive immunity, showcasing its ability to remember previous infections and respond more rapidly upon subsequent exposure to the same antigen.

While the inflammatory response, large lymphocyte production, and acute-phase protein production are integral to the immune system, they primarily fall under innate immunity or are part of the body's initial responses to infection. The inflammatory response is more of a general defense mechanism against a wide range of pathogens, and while large lymphocytes (such as natural killer cells) are involved in innate immunity, they do not specifically represent the adaptive immune system's focus on antigen specificity. Acute-phase proteins are also produced in response to inflammation and serve to enhance the innate immune response rather than providing a tailored response to specific pathogens.
