T cells of the immune system include cytotoxic and helper cells.

What is the role of helper cells in antibody formation?

The surface immunoglobulin that functions as the B-cell antigen receptor (BCR) serves two functions in B-cell activation.

  • First, when it binds antigen, it conveys signals directly to the cell's interior, similar to the antigen receptor on T cells.
  • Second, the antigen is delivered to intracellular locations by the B-cell antigen receptor, where it is degraded and returned to the B-cell surface as peptides attached to MHC class II molecules. 

The peptide is: The MHC class II complex can be identified by antigen-specific armed helper T cells, causing them to produce proteins that induce the B cell to proliferate and its offspring to develop into antibody-secreting cells.

  • In the absence of T cells, some microbial antigens can directly activate B cells.
  • They are activated on the surface of antigen-presenting cells, which develop during infection-induced innate immune responses.

Hence, the correct answer is option B
