Explanation / Answer

In alkanes only inter molecular forces are vanderwalls forces.in alcohols hydrogen bonding is also present .Hydrogen bonding is more stronger than vanderwalls forces.so boiling point of alcohols is greater than alkanes.molecule B forms more hydrogen bonds than C.so boiling point of B greater than C greater than A
