The correct answer is D) Why will I be writing?
The question that can help a writer analyze a prompt and develop a claim for an argumentative essay is "Why will I be writing?"
First of all, the author needs to know the purpose of its writing. If the author does not have a clear idea about the reason of its writing, it will be difficult to proceed. Once the author knows why he/she will be writing, he can understand the topic and elaborate on the arguments of its writing.
The other options of the question were A) Does the option restate the claim? B) Is supporting evidence is included? C) Is the claim clearly stated?
