Step 1
Mitosis and differentiation produce cells for growth and development.
Answer
The correct explanation lies in the process by which B cells become activated. When B cells are stimulated, they undergo mitosis to proliferate and differentiate into plasma cells, which are responsible for producing antibodies.
Option (D) closely describes this process: it highlights that through mitosis and differentiation, B cells develop into cells that play crucial roles in both the immune response and overall growth and development. This differentiation allows them to secrete antibodies that target specific antigens, providing an effective immune response.
