A compound A of formula C3H6Cl2 on reaction with alkali can give B of formula C3H6O or C of formula C3H4. B on oxidation gave a compound of the formula C3H6O2. C with dilute H2SOcontaining Hg2+ ion gave D of formula C3H6O, which with bromine and NaOH gave the sodium salt of C2H4O2. Then A is:

1. CH3CH2CHCl2

2. CH3CCl2CH3

3. CH3CHClCH2Cl

4. CH2ClCH2CH2Cl
