The correct answer is C.
(The nonspecific response provides an immediate response, while the specific response involves a delay between exposure and response.)
- The non-specific immune response is the first line of protection from different types of pathogens and microbes such as skin (physical barrier). It is immediate response however, it is not specifics and it does not involve the recognition of pathogens.
- The specific immune response depends on pathogen recognition and therefore is long-lasting immunity and it takes time to be effective. This response includes B- cells, T-cells, phagocytic cells and NK cells.
