Step 1: Plan:
I will sort the four writers by the type of play and then link the play to its author.
Step 2: Sort by type:
Aeschylus, Sophocles and Euripides wrote tragedies. Aristophanes wrote comedies.
Step 3: Remove the comedy writer:
Oedipus Rex is a tragedy, so Aristophanes is out.
Step 4: Recall famous plays:
Aeschylus is known for the Oresteia. Euripides is known for Medea. Sophocles is known for the Theban plays: Oedipus Rex, Oedipus at Colonus and Antigone.
Step 5: Conclude:
Oedipus Rex belongs to Sophocles.
Final Answer:
The answer is option 3, Sophocles.
