Question:

5. Which of the following reactions is a redox reaction? (a) K2CrO4 + BaCl2 ? BaCrO4 + 2KCl (b) Pb22+ + 2Br- ? 2PbBr (c) Cu + S ? CuS

The answer sheet says just C, but shouldn't it be B and C since Lead seems to be gaining an electron in order to bond with Br (ie it is going from 2+ to just 1+)? Please explain why I am incorrect if I am.
