Answer: D. No only
Step-by-step explanation:
To be honest, I am not really sure whether I get your question. However, by the choices given, I assume the question should be:
- _________ did she write the essay, but she also revised it.
If it is as above, then Not Only should fit in. This is a typical grouping of "Not only......but also......"
Hope this helps!! :)
Please let me know if you have any questions or I interpreted the question incorrectly.
