Homework Equations

The Attempt at a Solution

I am not sure about this question. I canceled out A and D because lead is a metal while carbon is a non-metal. However, I can't choose between B and C. Could someone give me some advice?

In general the differences between elements of the same group are more pronounced for the lighter elements. That's only a lousy rule of thumb though.
