What are the electronic configurations of Cr and Cu?

If they followed the trends of their neighbours, what would you have expected their electronic configurations to have been?

(Poor Q, BTW, they DO follow the rules. It is just that the rules you are applying are wrong. How dare your teacher tell them that they are not following the rules, they wrote the rules.)
