`C_(7)H_(14)` (A) decolourises `Br_(2)` in `CCI_(4)` and reacts with `Hg(Oac)_(2)` in THF `H_(2)O` following by reduction with `NaBH_(4)` to produce a resolvable compounds (B). (A) undergoes reductive ozonolysis to give the same compound (C) obtained by oxidation of hexan-3-ol with `KMnO_(4)` . Identify (A), (B), and (C).
