Answer:
D. agreement
Explanation:
It wouldn't be "agreements" because it says "a final" which suggests that there is only 1 agreement.
It wouldn't be "agree" because it wouldn't read right.
It wouldn't be "agreed" because that is past tense and they haven't yet reached an agreement.
So it would be D. agreement
