Statement I: Acquired immunity is naturally present from birth and is inherited from parents.

Statement II: The secondary lymphoid organs serve as the sites where lymphocytes interact with antigens.

Only statement II is correct .

The correct answer is Option is (2) - Only statement II is correct .

Acquired immunity refers to the immune response that develops throughout life as a result of exposure to pathogens or through vaccination. It is not present from birth and is not inherited from parents. Instead, it is acquired through various means, such as exposure to pathogens, vaccination, or transfer of antibodies from mother to child during breastfeeding.

Secondary lymphoid organs, including the spleen, lymph nodes, tonsils, Peyer's patches, and appendix, play a crucial role in the immune response. These organs provide specialized microenvironments where lymphocytes interact with antigens. When antigens are encountered in secondary lymphoid organs, lymphocytes undergo activation and proliferation, leading to the development of an immune response against the specific antigens. This response involves the production of effector cells, such as antibody-secreting plasma cells or cytotoxic T cells, which are responsible for targeting and eliminating the antigens.
