B- to teach lessons and explain why things happen
Step-by-step explanation:
The technology wasn't the best in Ancient Greece, so they had to rationalize their existence to the best of their abilities. Religons and belief of higher beings give people a sense of comfort and hope, so they created these myths to better their everyday lives and give themselves a purpose.
