A

Right.

Thank you Ms. Sue

You're welcome, Michelle.

The correct answer is:

b. run-on

Explanation:
A run-on sentence occurs when two or more independent clauses are joined together without appropriate punctuation or conjunctions. In this case, the sentence "Edgar Allen Poe invented the convention of the solution that is overlooked." and "Because it is so obvious." are separated by only a period, which is insufficient to link them properly.

To fix the run-on sentence, you could add a coordinating conjunction such as "and" or "but" between the two clauses: "Edgar Allen Poe invented the convention of the solution that is overlooked, because it is so obvious."

Alternatively, you could separate the two clauses into separate sentences: "Edgar Allen Poe invented the convention of the solution that is overlooked. Because it is so obvious."
