The alternative which presents an example of formak research is the following one:
B. interviewing an expert on your chosen topic.
Explanation:
If you interview an expert, it means you are looking for reliable, trustworthy information, and not rumors or guesses. It makes your research serious, that is, formal and seeking accurateness.
The other alternatives present too informal and even irrelevant things to do when it comes to doing an actual research. Letter C could be a pre-research thing, though- not the actual research.
