<span>The word which is not derived from the Latin
preposition “ex” is:</span>
D. extraterrestrial

from the word, the root word can still stand alone with its own meaning
considering its origin.</span>
ummm, letter D ? I honestly can't tell you if its right or not. sorry
I believe the pronoun "what" is already properly placed.
