Redox Reactions

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

CH4(g)+4Cl2(g)→CCl4(l)+4HCl(g)\mathrm{CH_4(g) + 4Cl_2(g) \rightarrow CCl_4(l) + 4HCl(g)}

  1. A.+4 to +4
  2. B.0 to +4
  3. C.−4-4 to +4✓
  4. D.0 to −4-4

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