Correct Answer - B
`CH_(3)CHO+HCH_(2)CHCH_(3) overset(NaOH) to`
`CH_(3) CH underset("Major")((OH))CH_(2)COCH_(3)+CH_(3)CH(OH)CH_(2)CHO+(CH_(3))_(2)C(OH)CH_(2)COOH_(3) +(CH_(3))_(2)C(OH)-CH_(2)CHO`
`underset("Major product")(CH_(3)CH(OH)CH_(2)COCH_(3)) overset(Delta) underset(-H_(2)O) tounderset("Major product (25%)")(CH_(3)CH=CHCOCH_(3))`
