• B. Bone marrow
• C. Plasma and lymph
• D. Cerebrospinal fluid

Answer 1

The correct option is C Plasma and lymph

Humoral immunity is the aspect of immunity that is mediated by macromolecules found in extracellular fluids such as secreted antibodies, complement proteins, and certain antimicrobial peptides. Humoral immunity is so named because it involves substances found in the humour (plasma or lymph) or body fluids. It involves antibody, so, it is often referred to as antibody-mediated immunity.

So, the correct answer is 'Plasma and lymph'.
