Correct answer: C. Your plan and the model you are using at the time
Explanation
The principle — a limit is a property of your plan and the model in front of you, and it is deliberately not a fixed published number.
Why the key is correct — OpenAI states that limits vary by plan and model and can change over time to keep performance stable, with higher tiers getting more headroom than lower ones.
Why the others are wrong — there is no single universal daily figure, since the allowance moves with tier and model. Nothing accumulates as a lifetime budget, because allowances refresh. And geography affects which plans you can buy rather than what a plan allows.
Remember this — if you hit a limit, the useful questions are which model you were using and which plan you are on.
