An organic compound (X) with molecular formula

\mathrm{C}_3 \mathrm{H}_6 \mathrm{O}

is not readily oxidised. On reduction it gives

\mathrm{C}_3 \mathrm{H}_8 \mathrm{O}(\mathrm{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-ol. Compounds

(\mathrm{X}),(\mathrm{Y})

and

(\mathrm{Z})

respectively are : An organic compound (X) with molecular formula C_3 H_6 O is not readily oxidised. On reduction it gives C_3 H_8 O(Y)

Options

A $\mathrm{CH}_3 \mathrm{COCH}_3, \mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{OH}, \mathrm{CH}_3 \mathrm{CH}(\mathrm{Br}) \mathrm{CH}_3$
B $\mathrm{CH}_3 \mathrm{COCH}_3, \mathrm{CH}_3 \mathrm{CH}(\mathrm{OH}) \mathrm{CH}_3, \mathrm{CH}_3 \mathrm{CH}(\mathrm{Br}) \mathrm{CH}_3$
C $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CHO}, \mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{OH}, \mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{Br}$
D $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CHO}, \mathrm{CH}_3$ \mathrm{CH}=\mathrm{CH} $_2, \mathrm{CH}_3 \mathrm{CH}(\mathrm{Br}) \mathrm{CH}_3$

Correct answer

B. $\mathrm{CH}_3 \mathrm{COCH}_3, \mathrm{CH}_3 \mathrm{CH}(\mathrm{OH}) \mathrm{CH}_3, \mathrm{CH}_3 \mathrm{CH}(\mathrm{Br}) \mathrm{CH}_3$
