Identify the set of reagents `//` reaction conditions `'X'` and `'Y'` in the following set of transformations.
`CH_(3)-CH_(2)CH_(2)Br overset(X)rarr P r od uct overset(Y)rarr`

Options

A. `X=` dilute aqueous `NaOH, 20^(@)C, Y = HBr//` acetic acid, `20^(@)C`
B. `X =` concentrated alcoholic `NaOH, 80^(@)C, Y = HBr//`acetic acid, `20^(@)`
C. `X=` dilute aqueous `NaOH 20^(@), Y = Br_(2)//CHCI_(3), 0^(@)C`
D. `X =` concentrated alcoholic `NaOH, 80^(@)C, Y = Br_(2)//CHCI_(3),0^(@)C`

Answer

B
