In Greek mythology, Prometheus’s theft of fire led directly to Zeus creating Pandora. Prometheus takes fire from the gods and gives it to humanity, providing humans with a powerful resource while defying Zeus’s control.
Zeus responds by ordering the creation of Pandora, who is fashioned by Hephaestus and equipped with qualities supplied by the gods. Pandora is sent to Epimetheus, Prometheus’s brother, and her arrival forms part of the punishment imposed on humanity. The jar episode follows this earlier act, so Pandora’s story is inseparable from the Prometheus myth.
The myth is sometimes reduced to a warning about curiosity, but Hesiod’s sequence is broader. It explains the origin of human troubles through a conflict between Zeus and Prometheus, with Pandora functioning as Zeus’s instrument of punishment. Prometheus is therefore the correct Titan in this question; Epimetheus is the Titan who receives Pandora, while Atlas and Menoetius belong to other Titan stories.
