Redox Reactions

What is the change in the oxidation number of carbon in the following reaction?

$C H_{4} (g) + 4C l_{2} (g) \to CC l_{4} (l) + 4HCl (g)$

A.+4 to +4
B.0 to +4
C. $- 4$ to +4✓
D.0 to $- 4$

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
