Which phrasal verb means to destroy something, especially a building?

• A. Knock down
• B. Demolish
• C. Extend
• D. Pull down

Answer: (D)

The main idea here is choosing a phrasal verb that means to destroy a building. The best fit is pull down, because this phrasal verb is specifically used to describe demolishing a structure by bringing it to the ground. It captures the sense of destroying a building in a concise, natural way, as in “The old theatre was pulled down to make way for a new development.”

Knock down is very close and also describes causing something to fall, but it’s a bit broader in use and can refer to other things besides buildings. Demolish is a standard single-word verb, not a phrasal verb, so it doesn’t meet the requirement of the question. Extend is unrelated to destroying a building.
