Correct answer: C. An assistant you build with your own instructions, files and chosen tools
Explanation
The principle — a custom GPT packages a way of working so it can be reused and handed to other people.
Why the key is correct — OpenAI describes building your own AI assistant with tailored instructions, uploaded files and access to selected tools, adding that these assistants behave like specialised versions of ChatGPT and can be shared or published to a public directory.
Why the others are wrong — nothing is retrained; it is configuration over the same model. It is not a snippet you paste, because it opens as an assistant already carrying its setup. And it is not a subscription tier.
Remember this — a project organises your own ongoing work; a custom GPT packages a repeatable job, and can be shared.
