C., the setting of a story provides the atmosphere and mood of a story
The correct answer among the choices listed above is option B. The incorrect use of the word insomnia is shown in the sentence "<span>At the banquet, every employee received a sweatshirt with the company’s insomnia on it</span>". Insomnia is a sleeping disorder and the use in sentence B is not correct.
I believe the correct is the third option. It is important to preview sources before using them in your research because it reveals deeper concepts. Reading deeply the sources would allow you to have a deeper understanding of the sources and determine which parts of the sources are useful to your research.
If you accept either C or D as the correct revision then you have to accept both of them. Hence the best way to treat the sentence is to ignore both of them.
B is not correct either. You can over punctuate.
That leaves A.
