The below I picked B. I agree with the explanation that its utility over beauty, but — to serve your workaday owners perfectly — would be to have good utility, no? If you look at the sentence structure, i thought B was also slightly better because “to serve” seemed more aligned with “employed” than “valued”. Employed kept the same structure as to serve from the prior sentence, with the same meaning of utility over beauty.
Is this a case where you just need to remember that function is more similar to “utility” which is what the GRE always chooses as an opposite to beauty?
