The correct answer is D. A presentation
Step-by-step explanation:
A presentation is a type of communication in which the main speaker explains to an audience a plan, product, idea, topic, issue, etc. This differs from other types of communication because a presentation is used in a formal context and often includes charts, images, diagrams, and similar that help the audience to understand the speaker.
In the case of Abril, a presentation is the best communication channel because through a presentation she can explain her plan to all the team at the same time; also, this is appropriate because she needs to includes charts and diagrams which are more commonly used in presentations. Besides this, a presentation allows the Abril's team to ask questions and have an immediate response in case they do not understand.
