Final answer:
A professional style is recommended for a speech to business leaders, with a formal and authoritative tone to convey credibility and maintain professionalism.
Explanation:
Professional style is the most suitable for a speaker preparing a speech for business leaders in the community. This style conveys a tone that is objective, neutral, courteous, and constructive, falling between formal and informal.
Using a formal style in the speech demonstrates that the speaker takes the institution they are representing seriously and meets the rigorous expectations of the audience. It requires the speaker to speak impersonally, maintaining a level of authority and professionalism.
An authoritative style, where the speaker delivers information confidently without involving personal pronouns, can help establish credibility and trust with the audience of business leaders.
