Answer:
The correct answer is letter "C": Choose a topic that he is interested in and wants others to know more about.
Explanation:
In case somebody has to create a presentation but is not sure what to talk about, the topic that person must choose has to be related to a matter of interest of the exponent and the audience. In that case, the exponent has great chances of going in detail about the topic without much effort because that information is possibly well-known by him or her, something that will give the exponent confidence at the moment of speaking.
