A (hypothetical) vaccine to protect against cholera consists of cholera toxin‘s B subunit. The
antibodies generated in response to this vaccine would confer protection against developing
cholera by:
A. Preventing binding of V. cholerae bacteria to the host intestinal epithelia
B. Preventing delivery of cholera toxin to the host cells
C. Preventing the activation of adenylate cyclase by G protein
D. Preventing the export of water and ions from the host epithelial cells
E. Facilitating the phagocytic destruction of V. cholerae via opsonization
