B cells respond to the initial antigen challenge by . forming of a large number of B cells and T cells that display surface antibodies different from the original B cell producing progeny cells that include plasma cells and memory cells with surface antibodies different from the original B cell forming of a large number of B cells and T cells that display surface antibodies identical to the original B cell producing pyrogens to initiate fever producing progeny cells that include plasma cells and memory cells with surface antibodies identical to the original B cell

Producing progeny cells that include plasma cells and memory cells

Explanation:

B cells are essential cells in the constitution of the body's immunity. These cells are responsible for developing the so-called humoral immunity that is capable of neutralizing and destroying foreign substances that do not belong to the organism, that is, the B cells are capable of destroying antigens. To destroy the antigens, B cells start a production of descendant cells that are made up of plasma cells and memory cells.

option c is the correct answer.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
