Answer 1

The correct answer is B). A thesis, or topic statement.  

The answer to a strong research question leads to a thesis or topic statement.  This is because if you have investigated properly, researching the facts and confirming the sources, then it can lead you to a thesis or topic statement.

A thesis defines the scope and purpose of the document. It must be argued, limited and unified. A correct topic sentence improves the organization of an essay for a better understanding.
