Which sentence uses profuse correctly to express abundance?

• A. I offered profuse thanks to the helpers.
• B. The rain was profuse across the city.
• C. The room was profuse in size.
• D. Her ideas were profuse and confusing.

Answer: (B)

Profuse means abundant or lavish in amount, used to stress a large quantity of something. In the sentence about rain, saying the rain was profuse across the city communicates a plentiful, widespread amount of rainfall, giving a clear sense of heavy precipitation covering a large area. This natural pairing of profuse with something that can be abundant—rain—makes the meaning straightforward and vivid. The other options either use profuse in less natural collocations (like in size) or describe things in ways that don’t convey abundance as cleanly, so the rain example best expresses the intended idea of plentifulness.
