Why (A) is wrong: say 20% of employees regularly eat at the cafeteria and everybody else eats out. They're the ones then who we're talking about--more of them chose mushroom casserole over the other dishes during those two days. Now imagine it's 80% of the company that eats in the cafeteria. Now, we're talking about those people--more of them chose mushroom casserole. Does the difference matter for the argument? No. The point of the argument is that of everybody who eats there--whether it's 5 people or 20 people--more of them chose mushroom casserole those two days so it should be served all the time. It doesn't matter how many total people are regularly eating in the cafeteria.
(B) is wrong because we're not concerned about ingredients.
(C) is right because the argument ignores this possibility. What if people chose the mushroom casserole because they like to change things up a bit? If that's true, then serving the casserole all the time means they'll stop picking it as much!
(D) is irrelevant. We're talking about main dishes.
(E) is like (D). We're talking about lunch.
