Identify the correct set of reagents or reaction conditions ' X ' and ' Y ' in the following set of transformation

Options

A(\mathrm{X}=) dil.aq. (\mathrm{NaOH}, 20^{\circ} \mathrm{C}, \quad $\mathrm{Y}=\mathrm{Br}$ _2 / \mathrm{CHCl}_3)
B(\mathrm{X}=) conc.alc. (\mathrm{NaOH}, 80^{\circ} \mathrm{C}, $\mathrm{Y}=\mathrm{Br}$ _2 / \mathrm{CHCl}_3)
C(\mathrm{X}=) dil.aq. (\mathrm{NaOH}, 20^{\circ} \mathrm{C}, \quad $\mathrm{Y}=\mathrm{HBr}$ ) /acetic acid
D(\mathrm{X}=) conc.alc. (\mathrm{NaOH}, 80^{\circ} \mathrm{C}, $\mathrm{Y}=\mathrm{HBr}$ /) acetic acid

Correct answer

D. (\mathrm{X}=) conc.alc. (\mathrm{NaOH}, 80^{\circ} \mathrm{C}, $\mathrm{Y}=\mathrm{HBr}$ /) acetic acid
