(B) The reaction proceeds in two steps: $1$. Treatment of $3$-hydroxycyclohexan-$1$-one with $PBr_3$ replaces the hydroxyl group $(-OH)$ with a bromine atom $(-Br)$ to form $3$-bromocyclohexan-$1$-one. $2$. Treatment of $3$-bromocyclohexan-$1$-one with alcoholic $KOH$ $(alc. KOH)$ induces a dehydrohalogenation reaction (an $E2$ elimination). The base abstracts a proton from the $\alpha$-carbon relative to the bromine,leading to the formation of a double bond between the $\alpha$ and $\beta$ carbons. This results in the formation of the conjugated enone,$cyclohex-2-en-1-one$.
