My opinion is the answers A and D. I would choose A if you can only choose one, though.
Answer: I believe the correct order is:
Create a box and title it as the “Home Page” → Branch out pages and specify navigation flow → Gather information such as text and images → Determine the title, heading, and content for each page → Draw a layout of each web page with its elements.
Explanation: It makes sense, you start with your "Home Page", then you follow the steps of planning to map out your site's navigation. You have to gather information about it before you have enough knowledge about it to determine the title, heading, and content. You also need to know the content to create a clean and workable layout for the page.
The question is a little vague. A normal hard drive, flash drive, and solid state drives can be considered all three.
