C. is the correct answer.
Answer and Explanation:
"Invictus" is a poem that portrays Ernest Henley's emotional control and resistance.
Henley wrote it when he was suffering from bone tuberculosis, a very serious and painful illness that could cause him to die in the blink of an eye, or torture him over time. When reading the poem, we can see how Henley was suffering, but he is very courageous and ready to face the disease with the greatest dignity possible, as he believed that the disease was not greater than him. We can see this through the line "My head is bloody, but unbowed."
