The correct idiom is 'function AS.' Eliminate (A) and (B).
(C) is incorrect because 'its' (a pronoun referring to the singular case) incorrectly refers to plural 'turtle species.'
(E) omits the verb 'function.' Because of the preposition 'AS', we are comparing verbs. The sentence should read "their horny jaws function as teeth function.' In standard English, you do not repeat the verb, but instead replace it with the 'do.'
Therefore, (D) is the answer.

Hi folks,
I’m afraid the correct answer for this one is choice E and not choice D.
Although the turtle has been toothless for more than 150 million years, in some contemporary turtle species the moderately sharp and jagged edges of their horny jaws function for teeth.
Per the context of the sentence, it is not difficult to understand that here turtle’s “horny jaws” are NOT compared to “teeth”. The horny jaws actually play the role/function of teeth. Hence, this sentence presents function of horny jaws.
PoE:
A. their horny jaws function for teeth: Incorrect.
1. Plural pronoun “their” does not agree in number with singular “turtle”.
2. Use of “for” is incorrect.
B. its horny jaws function for teeth: Incorrect. Use of “for” is unidiomatic.
C. its horny jaws function as do teeth: Incorrect. Notice that “as” is followed by a clause here, presenting comparison. This is not correct because the sentence does not compare the horny jaws with teeth.
D the horny jaws function as teeth do: Incorrect. Same as choice C.
E the horny jaws function as teeth: Correct. When “as” is used to present role/function of something/someone, it is followed by a noun entity. Here “as” is correctly followed by noun entity “teeth”. Hence, this is the correct answer.
P.S: To be able to get rid of the confusion of when to use “as” and when to use “like”, read the article by clicking on the following link:

Hey All,
Seems like there's still confusion on this one, so I thought I'd weigh in. There are two important splits to deal with here. The first is pronoun (singular/plural and pronoun/versus no pronoun) and the second is idiomatic.
"Although the turtle has been toothless for more than 150 million years" has no bearing on the rest of the sentence. The next clause begins with a new subject "some contemporary turtle species" (which is not an adverbial modifier, by the way), which is the most logical antecedents for any pronoun. Species is plural, so we would need "their", or else to remove the pronoun altogether. This is better, because there would be definite confusion between the two possible antecedents (turtle, species) anyway. From there, we need the right idiom, which is "x functions as y". There's no need for the verb "do", because that's obvious (i.e. I can say "The Tacoma Narrows Bridge ended up functioning as a real-life physics experiment", and don't need to say "The Tacoma Narrows Bridge Ended up functioning as a real-life physics experiment does".
This gets us to answer choice E.
Hope that helps!
