Answer 2

Explanation:

A substance that has a lower boiling point will evaporate first. Boiling points of given species are:-

1) Boiling point of water = 100 c

2) Boiling point of alcohol = 79 c (here ethanol is considered as alcohol)

3) Boiling point of petrol = 95 C

4) boiling point of kerosene = 150 C -300 C

Hence, the correct answer is

alcohol > petrol> water > kerosene oil
