Among the given options, the word that best describes the mood of Ulysses in Tennyson's poem of the same name is heroic. The poem is a remembrance of the life he lived as a hero and how his current unsatisfying life is surrounded by the nostalgia of the yearning for younger years:
"Much have I seen and known; cities of men and manners, climates, councils, governments (...) I am a part of all that I have met (...) How dull it is to pause, to make an end, to rust unburnished, not to shine in use!"
Yet we can observe how he evolves to show a more eager restless tone expressing his will to keep fighting and striving even not in the ideal circumstances of what used to be:
"We are not now that strength which in old days, moved earth and heaven, that which we are, we are; One equal temper of heroic hearts, made weak by time and fate, but strong in will to strive, to seek, to find, and not to yield."
