Answer:
A) central
Explanation:
The lymphatic system plays a major role in specific immune responses. The lymphatic system is composed of lymph, lymphatic vessels, and lymphatic organs (bone marrow, thymus, lymph nodes, spleen, etc). These lymphatic organs help to produce and repair immune cells including lymphocytes (T cells and B cells), monocytes, and plasma cells that generate antibodies against specific pathogens. The lymphatic organs can be classified into 1-primary (central) lymphoid organs, i.e., bone marrow and thymus, that produce lymphocytes and 2-secondary lymphoid organs, i.e., spleen, lymph nodes, and tonsils, that filter out and destroy undesired pathogens. The central lymphoid organs are sites where lymphocytes can divide and proliferate.
How may I be of assistance. The question is unclear.
It is either A or B because constructivism is building together
Systemic lupus erythematosus (SLE) is a rheumatic disease attributed to autoimmune mechanisms.
Systemic lupus erythematosus (SLE, lupus) is characterized by a global loss of self-tolerance with activation of autoreactive T and B cells, leading to the production of pathogen autoantibodies and tissue damage.
Innate immune mechanisms are required for aberrant adaptive immune responses in SLE. Recent advances in basic and clinical biology have shed new light on the disease mechanisms of lupus. This review article describes recent studies that provide valuable insights into disease-specific therapeutic targets.
Systemic lupus erythematosus (SLE or lupus) is a systemic autoimmune disease with inflammation of multiple organs. SLE is characterized by the production of pathogenic autoantibodies against nucleic acids and their binding proteins, reflecting a global loss of self-tolerance.
Loss of tolerance with subsequent immune dysregulation is the result of genetic factors in the context of environmental triggers and stochastic events, with recent studies implicating more than 30 genetic loci in disease pathogenesis.

I would say true because that teaches you to make goals that take longer to achieve.
