C. Practice.

Explanation:

Regardless of how fast technology is moving ahead and what resources may be available nowadays for presentations, it is a fact that the best thing one can do, is to practice your presentation several times before delivering it so that you can be familiarized with its contents, its flow, its sources and arguments, the media with which you prepare the presentation and, above all, any unexpected circumstance that may arise. Practice and preparation are the key.
