Option B. A theme that is found in both "We Wear the Mask" and "A Man Said to the Universe" is that each person is part of a larger system, such as society and the environment

Explanation:

Both "We Wear the Mask" and "A Man Said to the Universe" have a common theme of how every single person in the planet is part of a system, a community and an environment.

In the case of "We Wear The Mask" a poem written by Paul Lawrence Dunbar, the theme is portrayed by how black people are forced to portray a false sense of happiness and belonging in order to fit in a society, that it is very much still oppressive and unfair to them.

In "A Man Said to the Universe" a poem written by Stephen Crane a man asks to the Universe to be recognized, to be seen. And as the universe replies that it has no sense of obligation towards the man, the theme unveils itself as how hard and isolating it can be to be a human surrounded by millions of others, and still feel not seen. In order to gain that identity within the society, men need to create something, to be worthy of  recognition.
