I'd say the answer is b. The answers to your own questions.
This is because you'd need to grasp the concept of what you are reading to be able to understand questions about it that test your knowledge on it. If you know what is going on, it will be easier to answer given questions. Plus, the rest of the options don't necessarily go in a specific order, unless it is different at your school.
I hope this helps and have a great day! :)
