Answer:
b. A hopeful spirit
Explanation:
at the end of "the rainy day" he accepts the fact that there are going to be dark days he says, "be still, sad heart, and cease repining, behind the clouds is the sun still shining, thy fate is common fate of all, into each life some rain must fall, some days must be dark and dreary." he compares his own feelings to the bad day/rainy day and he accepts the fact that life will throw obstacles at him. While in "Invictus" it says "It matters not how strait the gate, how charged with punishments the scroll, i am they master of my fate, i am captain of my soul." the author has hope.
