Prince Zuko’s mother is named Ursa.
Ursa is the former wife of Fire Lord Ozai and the mother of Zuko and Azula. Although she is mostly absent from the original animated series, her history becomes central to the sequel comic The Search. Before marrying Ozai, Ursa was in love with an actor named Ikem in her hometown of Hira’a.
Ozai’s father, Fire Lord Azulon, ordered Zuko’s death as punishment for Ozai’s defiance. Ursa helped protect her son by creating an untraceable poison that Ozai used to kill Azulon. Ozai then banished Ursa, claiming that her removal was the price of sparing Zuko.
The names in the wrong options belong to other characters or relatives. Ilah was Azulon’s wife, while Kya is Katara’s daughter in The Legend of Korra. Ursa’s later story reveals that a spirit altered her memories and appearance; she lived under the name Noriko until Zuko found her and restored their connection.
