The correct answer to this question is E, Echo effect. This is also known as an echo chamber effect. This means that we, as people are more likely to be around those who have the same ideas and thoughts that we do. The people we are around will echo our beliefs, hence the name.

For example, a democrat may only watch CNN and read liberal publications and not watch or read any reports from the other side. This also goes for a Republican, who would only watch Fox News. This isn't good because the person will only have a biased viewpoint instead of looking at news from all perspectives.
