The creature vows to revere Victor as a deity if he provides assistance; hence, Option D is the right choice.
The monster states it will act "gentle and submissive to my natural lord and king" if Victor fulfills his part, which the creature believes Victor owes him. He urges Victor to consider himself as his Adam.
Additionally, the creature threatens to put Victor's family in danger if he does not comply.
On the other hand, the creature guarantees to leave Victor and his loved ones undisturbed if he meets the monster's terms. However, if Victor declines, the creature threatens,
"
I will work at your ruin, and will not cease until your heart is desolate, compelling you to regret the day of your birth."
