A) They stimulate B-lymphocyte activity.
B) They interfere with multiplication of stem cells.
C) They stimulate growth and differentiation of lymphoid cells into lymphocytes.

D
Feedback:
Interferons are substances naturally produced and released by human cells that have been invaded by viruses. They may also be released from cells in response to other stimuli, such as cytotoxic T-cell activity. Interferons do not stimulate B-lymphocyte activity, interfere with multiplication of stem cells, nor do they stimulate growth and differentiation of lymphoid cells into lymphocytes.
