A B C - pronoun reference is not proper
D - X function as Y is the right idiom

IMO E.

A - function for vs function as (E) , I will prefer function as.
B - Plural pronoun -> Its is incorrect.
C - Plural pronoun -> Its is incorrect.
D - no need of 'do'.
E - Correct.

I also chose E.

But would like to know more on why C and D are "incorrect"?

Are C and D "incorrect" or not preferred here?

Thanks.

C - Contemporary turtle species and its do not agree.
D - X function as Y do - wrong, X function as Y is the right idiom.

C and D are wrong because Jaws function as teeth . If you add "do" , Jaws function as teeth do , what function do jaws or what function do teeth do? Isn't it weird?
