Answer:
C. Listen to what is being said rather than assume that you know what they are going to say.
Step-by-step explanation:
A is incorrect because you don't listen to someone just to respond quickly. This makes it seem like that you're waiting for them to stop talking that way you can get out what you have to say. B is sort of correct but not completely. While your response does prove your insightfulness, you shouldn't be focusing on that. If you focus too much on one detail in the topic, some people may take it that you only heard a little bit about what they were talking about. Or, it could look like everything but that detail was boring or uninteresting to you. C is correct because listening to what they have to say is the right thing to do. If you listen to the person, you may find that you didn't know what they were going to say, or, you may learn some interesting things from that person. D is incorrect because you may think you know what someone is going to say but they were actually going to say something else and it looks like you're rude and impatient.
Hope this helps! :)
