Final answer:
The Chorus states that Polyneices came from Argos when he entered into battle against Thebes. The information corresponds to his portrayal in Greek tragedies such as Aeschylus' Seven Against Thebes, where he leads an Argive army.
Step-by-step explanation:
The Chorus in the Greek play mentions that Polyneices came from Argos when he entered into battle against Thebes. This detail is derived from ancient Greek literature where Polyneices is a significant character who leads an army against his city after being exiled. In literary works such as Aeschylus' Seven Against Thebes, Polyneices is often depicted as the son of Oedipus and the brother of Eteocles, with whom he was supposed to share the throne of Thebes.
The correct answer to the question presented is (B) Argos. Polyneices assembled a force in Argos and then led them to Thebes to claim the throne that was denied to him, which ultimately brought about the battle where both brothers died.
