Answer:

The correct answer is option D. A and C.

Explanation:

Lymphoid tissue is the body part that is an essential part of the immune system that provides immune response against different infection or pathogens and protects from these foreign bodies. These tissues are present in all over the body that includes spleen, adenoids, tonsils, lymph nodes and other parts.

Lymphoid tissues or organs are the sites of the proliferation of the macrophages and lymphocytes. These structures also assist in furnishing surveillance points for lymphocytes and macrophages.  

Thus, the correct answer is option D. A and C.
