Answer:
Option (ii) ground level is correct
Explanation:
When a fire breaks out in the house then the clean air is at the ground level as due to fire the polluted air gets hot.
The polluted air tries to move upward as its density is low due to fire particles available in polluted air.
The clean air does not contain any fire particle so it is cold with respect to polluted air so, its density is more and it remains on the ground level.
Option (ii) ground level is correct
