Answer:
Option). B cells produce different types of antibodies in each patient.
Step-by-step explanation:
B cells are cells of adaptive immune system that provide specific responses against pathogens. B cells have BCR (B-cell receptors0 on their surface, which are specific for different types of pathogens. So, B cells recognize each particular antigen and make specific antibodies to neutralize those pathogens.
As strep throat is generally caused by bacterial infections, Claire must has infected by bacteria. On the other hand, Jamie is infected by influenza, which represents a virus.
Hence, their B cells will produce different types of antibodies in them for different pathogens.
Thus, the correct answer is first option.
