Answer:
B. Odin feels knowledge that is not earned is worthless.
Step-by-step explanation:
Remember, from the story we are told that to gain knowledge of what was to happen in the future, Odin paid heavily with his right eye.
Mimi said, "There is a price to be paid. All who have come here to drink have shrunk from paying that price. Will you, Eldest of the Gods, pay it?" , then Odin replied, "I will not shrink from the price that has to be paid, Mimir,"
So he forces others to pay for knowledge in other for them to show how much worth they attach to it.
