Answer:
B). False.
Step-by-step explanation:
The given assertion would be characterized as false because microphones are highly recommended when you are addressing a large group of people and people at the back face trouble in hearing what you are conveying. The use of a microphone will ensure that the speaker's first and foremost responsibility to communicate to each and every individual in the audience effectively is fulfilled as people may have a negative perception of the speaker or his message due to discomfort or strain they face. Therefore, using the microphone will convey your ideas(as a speaker) more clearly, effectively, and positively to the audience. Thus, option B is the correct answer.
