B - Bravery
Although you didn't provide the passage, there are various reasons as to why bravery is the answer.
A is incorrect as the Odyssey never focused on democracy as shown through kings of many lands since Odysseus himself was the king of Ithaca with his son being the rightful heir of the throne.
C, knowledge, is incorrect as characters in the Odyssey never valued knowledge. The Odyssey was filled with battles and overcoming hardships, not gaining knowledge and wisdom, thus ruling out C as the possible answer.
D, relaxation, is an answer you can immediately rule out. Throughout the Odyssey, the stories and the movies, you can see that all characters are constantly bustling and working for whatever they hope to accomplish. Although they may value relaxation, they seem to value work more so.
Hope this helps!
