Answer:
D. All of the above
Step-by-step explanation:
Listening to others is an important part of communication. It's impossible for people to communicate and properly understand each other if they don't listen. All of us have had the chance to meet at least one person who didn't seem to be listening to us at all. These conversations always end up frustrating for the person who is not being listened to, which often results in them stopping to care about the relationship.
All of the statements are true. Listening to others is a skill that people can learn or improve upon. Just like all skills, it's something that can be worked on. Many people have difficulties with listening and improve with time. This is necessary because, unless they improve, they will be unable to easily work with other people.
This is why option D is the correct one.
