Answer:
D. Including opinions.
Explanation:
Biased reporting is when a distorted report of any research is given. In other words, we can say that biased reporting is when there is any change in the research findings which may alter the report or present falsified facts about it.
Among the given options, biased reporting would be a result of a report that includes the personal opinions of the author. This is because if the report contains any personal opinions of an individual, then that means that report is leaning toward one side of the argument rather than presenting a neutral report.
Thus, the correct answer is option D.
