Correct answer: B. The free tier is a real product; paying mainly raises limits and models
Explanation
The principle — ChatGPT plans differ by how much and how new, not by which features exist.
Why the key is correct — OpenAI describes Free as core ChatGPT with basic limits, and Plus and Pro as access to the latest models and tools with higher limits. The free tier is the product with a smaller allowance, not a preview of it.
Why the others are wrong — there is no trial window to elapse, since free accounts continue indefinitely. Personalisation and projects are not paywalled: custom instructions are available on all plans, and projects on all free and paid subscription types. And history is not tiered, because chats are saved until you delete them.
Remember this — start free, learn the tool, and upgrade when you actually hit limits.
