Correct answer: C. A session-based limit, which resets every five hours
Explanation
The principle — a free-plan limit is a short rolling window, not a day and not a month.
Why the key is correct — Anthropic states that the free plan has a session-based usage limit that resets every five hours. Hitting it at eleven means the afternoon is available again, which changes what a sensible response looks like.
Why the others are wrong — nothing resets at midnight or on the first of the month, and opening a fresh chat does not clear a limit that is counted across all of them.
Remember this — when the limit lands, the useful question is how many hours, not how many days.
Sources — Anthropic's getting-started guide and its article on usage and length limits.
