Answer:
C. Plasma cell.
Explanation:
Acquired immunity is developed in the body following a previously encountered infection. The innate immunity by definition, always present in the body and is used to attack all general forms of infection.
The granulocyte cells are considered part of innate immunity and help mediate the immune response against foreign pathogens. These cells include basophils, neutrophils, eosinophils, mast cells, and macrophages (which are differentiated from monocytes).
The adaptive immune response involves the production of antibodies against specific target antigens. Plasma cells are an integral part of the adaptive response and secrete large volumes of antibodies in response to a secondary infection by a previously encountered pathogen. T-cells and B-cells are also part of the adaptive response.
