Identify the set of reagent / reaction conditions X and Y in the following set of transformations. \[C{{H}_{3}}-C{{H}_{2}}-C{{H}_{2}}Br\xrightarrow{X}\text{Product}\xrightarrow{Y}\]\[C{{H}_{3}}-\underset{Br}{\mathop{\underset{|}{\mathop{CH}}\,}}\,-C{{H}_{3}}\]

A)  X = dilute aqueous \[NaOH,\]\[20{}^\circ C;\]Y = HBr/acetic acid, \[20{}^\circ C\]

B)  X = concentrated alcoholic\[NaOH,\]\[80{}^\circ C;\]Y = HBr/acetic acid, \[20{}^\circ C\]

C)  X = dilute aqueous \[NaOH,\] 20°C; Y =\[B{{r}_{2}}\text{/}CHC{{l}_{3}},\,0{}^\circ C\]

D)  X = concentrated alcoholic\[NaOH,\]\[80{}^\circ C;\]Y = \[B{{r}_{2}}\text{/}CHC{{l}_{3}},\,0{}^\circ C\]
