Answer:
Athena gives Perseus a mirror so he does not look directly at Medusa.
Step-by-step explanation:
The story of Perseus and his quest to get Medusa's head is one act of courage and determination. This Greek mythology depicts numerous elements of Greek society like hospitality to guests, gods helping mortals in their quest, giving gifts, etc.
Perseus accepted the challenge of King Polydectes to get Medusa's head as a gift for his marriage with his mother, Danae. He did this not because he approved of their marriage, but he wanted to prove himself. And in his quest, he was helped by Hermes and his sister, Athena. the goddess of wisdom and war gave him a polished shield, which will act as a mirror to see Medusa. This was because looking at Medusa directly in the eye turns anyone into stone. This also shows how the Greeks valued intelligence, which is reflected in the acts of the gods. And this helped Perseus to be successful in his quest.
Thus, the correct answer is the fourth option.
