When a news story only presents one side, it is obviously the side the reporter supports. A. Bias by Spin B. Bias by Labeling C. Bias by Selection of Sources D. Bias by Placement

C. Bias by Selection of Sources.

Explanation:

Media bias or bias in the media is the different forms by which there are various angles through which the media addressed or tackle the news information that they got and present. These media biases are capable of spinning the tone and direction of the information and even the opinion of the readers.

When a news reporter decides to present only one side of a story that their reporter supports, then it is a bias by selection of sources. This bias can include more than one source but which all have or support the same idea and thus, share the same opinion about the particular theme or topic. This greatly is a one-sided presentation, leaning more towards the source that the reporter supports and not much into the other side.

Thus, the correct answer is option C.
