Why is B correct

Thanks for your question @AnanyaK Fredrick's statement is that "Art museums ought to devote their limited resources to acquiring the artwork of recognized masters." Because he does not mention genres at all, we can surmise that he does not consider genre representation an important criteria for what museums should be seeking to acquire. He thinks that looking for the works of recognized masters is the important criteria. We already know that Elaine believes genre representation to be an important criteria for what art museums ought to look for. This is where they would likely disagree.

Hello - thank you for the above, that is very helpful. Please could you explain why D is incorrect here? Thank you!
