Answer : 1. "oil cuts off oxygen supply, thereby stops the breeding of mosquitoes "
Explanation :
The growth or breeding of the mosquitoes can be stopped by spraying the kerosene on the water. This happens because when we spray the kerosene then the oxygen supply to the larva (small mosquitoes) stops and they die in the water. Spreading oil over water cuts the oxygen supply, hence mosquitoes cannot breed in them.
