A would not be suitable because asking yourself the subject of the text should be something you do before you read, in order to be prepared for the text and establish your purpose for reading it. B would not be suitable because that, again, should be something you do before you read, in order to be prepared for what you do and do not already know about the material and establish your purpose for reading it.
