Which element most establish a speaker's tone when giving a speech? a. sources
b. physical gestures
c. use of logic
d. circular reasoning

The correct answer is B.

Body language is an important factor while giving a speech. When a speaker communicates with the audience, he is not only limited to his words, the speech is a combination of words, verbal delivery and body language.

Using physical gestures makes the speech seem more compelling and trustworthy. Hand gestures help to emphasize certain points of the speech and strengthen the speaker's message. People pay attention to movements and gestures during speeches. The speaker can purposely use his body to stress a certain idea and the audience, seeing him doing so, is more likely to remember his words.
