Dear student,
 
 
A substance that has a lower boiling point will evaporate first. Boiling points of given species are:-
1) Boiling point of water = 100oC
2) Boiling point of alcohol = 79oC (here ethanol is considered as alcohol)
3) Boiling point of petrol = 95oC
4) boiling point of kerosene = 150OC−300oC
Hence, the correct answer is B.
