Explanation:

Presentation can be defined as an act of talking or speaking formally to an audience in order to explain an idea, piece of work, project, and product with the aid of multimedia resources or samples.

Basically, any speaker who wish to create an effective presentation should endeavor to interact frequently with the audience by holding a conversation.

This ultimately implies that, to create an effective presentation, speakers are saddled with the responsibility of interacting more often with the audience by taking questions, making a joke, getting them to repeat informations loud at intervals etc.

Additionally, speakers are advised to be passionate and show enthusiasm during their presentation because it would enhance their ability to speak confidently and as such leading to an engaging presentation.

Hence, the "Three C's" that should be possessed by a good or professional speaker are Character, Competence and Charisma.
