No the Answer Was B
A very bright student told me that he did 50 % 50 % but he himself asures the answer was B
dont really remember the percentages :/

It wasnt 50% 50%. it was 60 something and 30 something i think. it was a sodium salt plus alcohol.

A.. nucleophilic substitutition with NaOH then oxidation by Cr2o7/h+ since number of carbon didnt change
