Your company has an open$-$plan environment with shared working and meeting spaces.

You host an informative presentation for your investors in an informal meeting space in which attendees sit on couches. There is no audio$-$video equipment in the meeting space, so you distribute printed copies of the meeting agenda and a high$-$level slide presentation describing features and benefits of the company's new software. At the end of the presentation, the investors seem unclear about the specifics of the software.

Which of the following environmental factors would most efficiently clarify the information for the investors?

A$.$ A meeting room with tables to allow the investors to more easily take notes.

B$.$ A projector to allow you to demonstrate the use of the software.

C$.$ A longer presentation session to allow you more time to interact.

D$.$ A microphone to enhance the volume of your voice.
