Answer:
A. Lyric poem.
Explanation:
A lyric poem is a form of poetry in which the speaker/ poet talks of his personal feelings and expresses his innermost emotions. It conveys a powerful feeling through the first-person narrative voice and is usually a short, song-like manner.
William Ernest Henley's poem "Invictus" is one such lyric poem where he talks of a man's strength and endurance amidst a series of unfortunate events. It is a strong-spirited poem, where the man "thank[ed] whatever gods may be" for his "unconquerable soul". This shows his persistence, holding his head high, and not letting his 'unfortunate' life events pull him down.
Thus, the correct answer is option A.
