Question

Quizplus · Accepted Answer

For a B cell to become an antibody-secreting plasma cell, it must first bind to an antigen with its B cell receptor (BCR). Then, a T-helper cell with the same specificity as the B cell must also bind to the antigen and activate the B cell. This interaction triggers the B cell to undergo clonal expansion and differentiation into either memory B cells or plasma cells that secrete antibodies. Therefore, choice B is the best answer.
