Correct answer: B. Summarise it, extract information from it, or answer questions about its contents
Explanation
The principle — attaching a document changes the question you are able to ask, because the assistant is now working from your material rather than your description of it.
Why the key is correct — OpenAI states that you can upload files such as PDFs, presentations or plain text documents, and that ChatGPT can then summarise, extract information, or answer questions based on the contents.
Why the others are wrong — the contents are read rather than merely inspected as a file. Conversion is not the purpose; what comes back is reasoning about the material. And attaching supplies the document to the assistant, not to other people.
Remember this — describing a document is always weaker than supplying it. Attach the thing itself.
