Consider the following organic synthesis scheme:

Which step is matched with a correct reagent and set of conditions?
Step 1: Dilute aqueous H2SO4\text{H}_2\text{SO}_4H2SO4 heated under reflux
Step 3: KCN\text{KCN}KCN in aqueous ethanol heated under reflux
Step 4: Dilute NaOH\text{NaOH}NaOH solution at room temperature
Step 5: CH3OH\text{CH}_3\text{OH}CH3OH with an aqueous NaOH\text{NaOH}NaOH catalyst
