Answer:
Perseus is sent on the quest for Medusa's head due to a combination of factors. Firstly, the king, who is also Perseus's grandfather, requests him to bring it as a gift for the queen. This request is made because the king fears that his wife, the queen, may fall in love with another man due to her beauty. By possessing Medusa's head, which has the power to turn anyone who looks at it into stone, the king hopes to protect his wife from potential suitors.
Secondly, Perseus eagerly offers to bring Medusa's head as a gift to the king's wedding. This offer is made out of a sense of duty and honor towards his family. Perseus understands that by completing this dangerous task, he can prove himself as a hero and gain recognition among his people.
Furthermore, in some versions of the myth, Perseus promises to bring Medusa's head to the king in a fit of anger. This promise is made after the king boasts about his own bravery and belittles Perseus's abilities. In response, Perseus vows to slay Medusa and present her head as proof of his courage.
Lastly, Perseus's friends inform the king that he is the only hero capable of slaying Medusa. They recognize Perseus's exceptional skills and unique attributes that make him suitable for this perilous quest. These attributes include his divine parentage (being the son of Zeus) and possession of various magical artifacts such as a sword from Hermes and a shield from Athena.
In summary, Perseus is sent on the quest for Medusa's head because the king requests it as a gift for the queen's protection, Perseus offers it willingly out of duty and honor, he promises it in anger towards the king's arrogance, and his friends recognize him as the most capable hero for this task.
