You haven't given any of the options. That's like me asking you how many shoes there are with your eyes closed, so Ill just give an example.
Example:
Expository writing is writing that seeks to explain, illuminate or "expose" (which is where the word "expository" comes from). This type of writing can include essays, newspaper and magazine articles, instruction manuals, textbooks, encyclopedia articles and other forms of writing, so long as they seek to explain.
