Identify the set of reagents/ reaction condition ‘X’ and ‘Y’ in the following set of transformations :
`CH_(3)-CH_(2)-CH_(2)Br overset(X)to "Product" overset(Y)to CH_(3)-underset(Br)underset(|)CH-CH_(3)`

Options

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