Correct option is
A

The bottles will collapse because air outside the bottle will exert extra pressure

The bottles will collapse because air outside the bottle will exert  extra pressure.
When kept inside the refrigerator, the water vapors inside the bottle will condense, leaving a lot of empty space inside the bottle. The air outside the bottle will exert extra pressure which would lead to the bottle collapsing.
