A Correct answer
Explanation

Yes, it is correct. When boiled water is filled in the water bottle and its mouth is closed,  followed by cold water being poured over it, the bottle gets distorted. This happens because air inside the can gets condensed and creates low pressure. The high pressure from outside distorts the shape of the bottle.
