Correct answer: A. It grounds answers in live web content, with citations you can check
Explanation
The principle — search changes what Claude can see, not what it is.
Why the key is correct — Anthropic describes web search as expanding Claude's knowledge with real-time data to support better-informed decisions, and states that every response includes citations so you can verify sources yourself.
Why the others are wrong — the feature is not about length, nothing is written back into the model, and Claude is not replaced by a search engine.
Remember this — turn it on for anything current, then follow the citations before you rely on it.
Sources — Anthropic's web search documentation.
