Explanation:

• Crawling low under smoke is a valid guideline as smoke rises and the air is cleaner lower down.
• Feeling a closed door and using an alternate way if warm is correct as a warm door indicates fire on the other side.
• Staying in the room with the door closed and signaling for help when the exit route is unsafe is also a proper safety measure.

Answer:

All of the given options are correct guidelines to follow in the event of a building fire.
