Answer: c. Boredom and restlessness
Explanation:
In the poem Ulysses by Alfred Lord Tennyson, Ulysses or Odysseus as he is otherwise known, has made it back to Ithaca and has stopped exploring the world.
He is now aged and despises his position as the King of Ithaca which has forced him to settle on the island and enforce laws on people he considers uncivilized.
He is bored and restless with his life and yarns to go back to his time exploring when according to him, he felt true joy even in the moments of suffering.
