You didn’t show the poem but by the name it seems like Answer choice #1 (may be about self reflection)
Answer:
L
Explanation:
In the context I'm seeing it in, L seems like the most logical answer here.
Introvert= Less sociable, keeps more to self
Extrovert= outgoing, sociable
Personally-
I would say I am about 60% an introvert and 40% and extrovert. When I am at school, I try to keep more to myself. I like to be by myself and focus on schoolwork. When I am with friends I tend to be more extroverted because I am comfortable with them. I talk more, not only to them, but also to people i do not know.

Dr. King is decrying the fact that a hundred years after that Proclamation was made, the people who it was supposed to free were still being viewed through the eyes of racial inferiority and were therefore considered unequal in society.
