But I thought that it was hot steam, so high temperature means low pressure and when it comes in contact with cold water(high pressure), it sinks. I didn't think about steam getting condensed and causing reduction in pressure. Well, we should check both the points. Anyways, according to me, both conclusions are correct. That is hot and cold (difference in pressure by temp) and reduction of air pressure, both are correct. So it can be either option A or D

reason :the initial air was driven out of the bottle as the steam occupied the space inside. When it was emptied and capped tightly , some steam still remained inside the bottle. when cold water was poured over it , the steam condensed and turned into water droplets , which cause the reduction in air pressure inside the bottle. That is why , as the air pressure inside was lesser than the outside one , the bottle got crumpled (shrinked) to compensate the lose of air pressure. That is why both the options are correct.
