Answer:
(B) keep quiet while the other person is talking and avoid expressions such as "uh-huh."
Step-by-step explanation:
In a dialogue, of course each person has a moment of speaking and this must be respected. However, in order for attention to be given properly, attention must be paid to the interlocutor, maintaining eye contact, giving body signals of understanding and applying reflexive listening - which consists in listening carefully to what the other person says, understanding and repeating ( in his own words) to him for confirmation. This makes the person being heard feel that they have been understood and can give even more details about what happened. However, just listening without interacting and giving "uh-huh" beeps can give your caller a sense of disinterest, as if you want to get rid of the subject and the person as quickly as possible.
