The sentence which states implicit information that we learn from the passage is:
B. Odysseus is a generous leader.
In Book 9 Odysseus tells his stories of wanderings to Phaeacians. He tells him that the wind threw him and his men to Ismarus which was the city of the Cicones. The men lived on the land plundering around for food until the people of Cicones attacked them. Though Odysseus and his men escaped from the land six men from every ship went missing. Odysseus made all the arrangements for his people by killing the Cicones and saving them from their attack. This highlights the implicit information about Odysseus that he was the king who would do anything for his people.
