Briggs and King's experiments involved removing the nucleus from a frog egg and replacing it with a nucleus from an embryonic cell at various stages of development. They found that the cytoplasm of the egg could control the fate of the transplanted nucleus, indicating that the cytoplasmic environment can influence gene expression and cell differentiation. This supports choice B.
