Select the most appropriate option to fill in the blank.

The roof of the old building ______ during the storm.

collapsed

The most appropriate option to fill in the blank is collapsed.

The sentence is about the roof of an old building falling down during a storm. The word "collapsed" means to fall down suddenly and completely. It is the most appropriate word to use in this context because it conveys the meaning of the roof falling down in a sudden and destructive manner.

The other options are incorrect.

• Destroyed means to completely ruin or demolish something. This is also a possible option, but it is not as specific as "collapsed."
• Demolished means to tear down or destroy something completely. This is not as appropriate as "collapsed" because it implies that the roof was intentionally destroyed.
• Scratched means to mark or damage something with a rough or sharp object. This is not appropriate in this context because it does not convey the meaning of the roof falling down.
