Bettina was asked to give a presentation to a group of potential investors. She wouldn't find out what specifics they wanted her to discuss until she collected their questions a few moments before the presentation. What type of delivery must Bettina use in this situation?

Impromptu Style

Explanation:

Theoretically, an "impromptu" speech is "made up on the spot." It is unprepared and unrehearsed. There are many occasions when there is little or no opportunity to prepare.

Impromptu speeches are generally short and are often given with little or no notice. Notes are rare and the speaker generally looks directly at the audience.

It is fair to explain that "impromptu" describes a range from absolutely no preparation, to a modest amount of preparation (mostly thought) and rarely incorporates research or the formalities of outlines and citations that more formal speeches would include.
