This is a language structure problem and it must be answered correctly in such a way as to convey the exact meaning of the author so intended

Option A - Incorrect
The prepositional linkage is missing here. Between consists and the subsequent noun word(s) there should have been a suitable preposition like "of''to convey the message across.

Option B - Incorrect
This is grammatically wrong because the first line does not show posses while the second does. it is not necessary in this context it has been used.

Option C - Incorrect
It would have been correct if the subject used here had been "comprise" instead of "consists" . Whereas "comprises" does not require the preposition "of", "consist" does. It is lacking here .

Option D - Incorrect
As we have in the option B above, so also does it appear here. The possessive subject "of" aligns with the second nominal word i.e "twelve citizens". Same cant be said of the first noun word. lacking in construction.

Option E - correct
Here , the suitability of the preposition word "For" in this context is aptly appropriate and fitting. Also, the "consists" part now take shape with the addition of "of" to check its appropriateness
