I believe it is A. I am pretty sure that B and C are wrong because of the oxidation numbers not equaling zero.

Am I correct in my thinking?

What "C" are you talking about...??There's a $Cl$ which is the chemical symbol for Chlore...

Answer the question regarding the ON-s...

By the process of elimination.....

Seriously, though, I don't understand this concept. Can you just explain it to me?

Anyways, thank you for your time and effort if you are too busy.

The chlorate radical $ClO_{3}$ has ON $-1$ ,simply because the oxygen has ON $-2$ (as in most of its compounds) and the chlore has ON $+5$ (and you should figure out from the suffix "ate" and the lack of any prefix).
On the other side,the copper atom has ON $+2$ (because the problem says so,it may have ON $+1$ as well).
So to form a NEUTRAL MOLECULE,you need two radicals and one copper atom...
