An organic compound (X) with molecular formula C3H6O is not readily oxidised. On reduction it gives C3H8O(Y) which reacts with HBr to give a bromide (Z) which is converted to Grignard reagent. This Grignard reagent on reaction with (X) followed by hydrolysis give 2. 3-dimethylbutan-2-oI. Compounds (X). (Y) and (Z) respectively are:

(A) CH3CH2CHO, CH3CH=CH2, CH3CH(Br)CH3
(B) CH3COCH3, CH3CH2CH2OH, CH3CH(Br)CH3
(C) CH3CH2CHO, CH3CH2CH2OH, CH3CH2CH2Br
(D) CH3COCH3, CH3CH(OH)CH3, CH3CH(Br)CH3
