Sodium borohydride is known to reduce ketones and aldehydes, and in this case, it will reduce the \u03b1,\u03b2-unsaturated ketone to form an alcohol. The major product of this reaction will be 4-phenylbutan-2-ol, as the reduction will occur at the carbonyl carbon, leading to the formation of the corresponding alcohol."}
