A good method to use when choosing a research topic is:

c. Narrow your topic.

Explanation:

Probably the research topic is not the problem for selecting, in change, maybe the theme selected could be very extensive, for that reason, the best form is narrow the topic, it can be using the  method "for what", you can ask yourself so many times "for what" until you don't encounter another reason, at that moment, you'll know that the topic is the correct.

Obtaining information from document sources or thesis statements can introduce you to a topic that you don't enjoy, the reason why the investigation won't be successful at 100%.
