Which statement about the following paraphrase is correct?

These represent five of the six criteria air pollutants that the Clean Air Act monitors $($Gasp$,2017).$

a$.$

"Clean Air Act" should be in quotation marks because it is the name of a law enacted by Congress.

Although the phrase "five of the six criteria air pollutants" contains common and shared language, it requires quotation marks because so many of the source words are used together.

Because several sentences in the paragraph are from the same source, no citation is necessary after this sentence; one citation can appear at the end of the paragraph.

d$.$

None of the statements are correct.

e$.$

All of the statements are correct.
