• D. All the above

Answer 1

The correct option is D All the above

The acquired immune system, also known as the adaptive immune system is a subsystem of the overall immune system that is composed of highly specialized, systemic cells and processes that eliminate pathogens or prevent their growth. Acquired immunity creates immunological memory after an initial response to a specific pathogen, and leads to an enhanced response to subsequent encounters with that pathogen. Acquired immunity distinguish between self and non-self and produce antibodies against the non-self antigen.

So, the correct answer is 'All the above'.
