(B.) WCTU.

I chose B is this right?

Yes, that's right.

the answer is b

Yes, you are correct. The correct answer is B. WCTU, which stands for the Women's Christian Temperance Union. The WCTU was a reform-minded organization that focused on social issues related to alcohol, such as drunkenness and its impact on families and communities. They advocated for temperance and prohibition, and worked towards promoting sobriety and combating alcohol-related problems. So, if you were a reform-minded person who strongly disliked the social issues associated with alcohol, you would likely have been sympathetic to the WCTU and its goals.
