Answer:
Athena gives Perseus a mirror so he does not look directly at Medusa.
Step-by-step explanation:
In the Greek myth of Perseus, Perseus's mother, Danae was to be wedded to King Polydectes forcefully. The king, desirous of getting rid of his future wife's son, sent him on a quest to get Medusa's head as a wedding gift. Perseus agreed to the request, to prove himself.
And in the attempt to get Medusa's head, Perseus was helped by the gift that the goddess of wisdom and war, Athena gave him. The gift was a highly polished shield to act as a mirror so that Perseus should not have to look Medusa in the eye, for whoever looks in the eye gets turned to stone. This shows how the Greeks valued intelligence and, thus, helped Perseus triumph in his mission.
Thus, the correct answer is the fourth option.
