This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Biochemistry
The fusion of a myeloma cell with an antigen sensitized B cell lymphocyte is termed? 
Select and explain. 
A. Dendritic cell, B. Opsonization, C. Natural killer cell, D. Hybridoma
D: Hybridoma
Answer: D: Hybridoma 
Explanation: The usefulness of hybridomas arises from their ability to produce abundant monoclonal antibody to specific antigens. Natural killer and null cells are types of lymphoid cells. Dendritic cells may possess weak phagocytic activity and may be helpful in antigen presentation. Opsonization is the coating of antigens, usually bacterial, with complement fragments to enhance phagocytosis. Ref: Murray R.K., Jacob M., Varghese J. (2011). Chapter 50.
