I'm thinking that C. is the answer. The Ancient Greeks believed in Polytheism, or the worship and belief in multiple Gods. They used the Gods to explain natural but explainable occurrences such as disease or drought. they feared that if they did not appease the Gods, that they would bring death upon them. I hope this helps :)
C. do to everything that happens on earth happens because of them like how famine had to do with the harvest goddess Hera getting sad her daughter got kidnapped by Hates. that caused famine or an angry Posiden caused rough seas And Zeus thunderstorms
