HS- and H2O2 (or NaOH) are typically used for the conversion of dienes to allylic alcohols. In this case, HS- would attack at the more substituted carbon of the diene, leading to the formation of an intermediate enolate. Protonation of the enolate followed by oxidation with H2O2 would give 3-penten-2-ol. The other reagents listed are not appropriate for this transformation.
