I'd say that the correct option is d
Since it's the only option that is grammatically consistent with the second part of the sentence ("when materials containing ... are only partially combusted")

(D) carbon monoxide is formed when

The key to solving this is to ignore the modifier since it's not underlined. So let's read the sentence without "or carbonaceous materials"

A) from...are only partially combusted - incorrect
B) formed by materials...are only partially combusted - incorrect
C) the formation of carbon monoxide is when.... - too wordy
D) Looks good
E) when it's materials containing carbon... - who's material are we referring to here? That's a bad pronoun. Incorrect.

(B) carbon monoxide is formed by

(C) the formation of carbon monoxide is when

(D) carbon monoxide is formed when

(E) carbon monoxide forms when its


KAPLAN OFFICIAL EXPLANATION:



As we saw in number 17, this sentence begins with a modifier. Unlike the modifier in that sentence, this one is used correctly because it does indeed modify carbon monoxide. Eliminate (C) for creating an error where there was none. Next, you need to decide whether from, by, or when should end the underlined section. When you originally read the sentence, you probably noticed that something was very wrong. Since you can't change the end of the sentence, you need to alter the underlined portion in order to make the sentence grammatically correct. Only when does that (try reading them in), so eliminate (A) and (B). Finally, (D) is better than (E) because in this case the passive is formed is more accurate than forms and because the its in (E) is unnecessary. Go with (D).
