(D) The reaction of an alkene with cold,dilute,aqueous $KMnO_4$ (Bayer's reagent) results in syn-dihydroxylation,where a double bond is converted into a vicinal diol (two $-OH$ groups are added across the double bond).In the given compound,$5-$allylcyclohex$-3-$ene$-1-$ol,there are two double bonds: one in the cyclohexene ring and one in the allyl side chain.$1$. The double bond in the cyclohexene ring undergoes dihydroxylation,adding two $-OH$ groups.$2$. The double bond in the allyl side chain also undergoes dihydroxylation,adding two more $-OH$ groups.$3$. The original molecule already contains one $-OH$ group at the $1-$position of the ring.Total $-OH$ groups = $1$ (original) $+ 2$ (from ring double bond) $+ 2$ (from side chain double bond) = $5$ hydroxyl groups.

The organic compound $5-$allylcyclohex$-3-$ene$-1-$ol is reacted with cold,dilute,aqueous solution of $KMnO_4$. The total number of hydroxyl group$(s)$ $(-OH)$ present in the product is
