Which ancient Greek playwright, featured in "The Symposium," proposes that humans are in search of their other half to become whole?

Explanation

The correct answer is Aristophanes. In Plato's "The Symposium," Aristophanes presents the idea that people are constantly looking for their missing halves to feel complete. The other playwrights listed—Aeschylus, Sophocles, and Euripides—do not put forth this concept in the dialogue.
