I don't mind.What's your idea??

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?

NO.
What is the ON for each element...??What about the radical "chlorate"...??

What is C?

 

[dextercioby]

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

Answer the question regarding the ON-s...

Daniel.

Sorry, answer choice B.

Don't HIT AND RUN...How did u figure it out...??What was your logics??

Daniel.

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...
