The event that most clearly contributes to the monster's hatred of humans is option D: Frankentein's abandonment of his creation immediately after it receives life.
The monster tells it's story to his creator, Victor Frankenstein, when they meet on a hill. Frankenstein is surprised to see how articulated the creature is, and it tells how he was attacked every time he found humans. Then he narrates how he hid himself in a warehouse of firewood attached to a cottage, from where he observes the life of a family, until the day they discover the monster he is. From this point, the creature decides to get revenge from his creator.
