What spring did Asopus grant to Sisyphus?

Sisyphus, a figure from Greek mythology known for his cunning and for being condemned to an eternal struggle of rolling a boulder uphill, is associated with the spring Pirene. According to myth, Asopus, the river god, granted this spring to Sisyphus in connection with the legend of Sisyphus's efforts to capture Asopus's daughter, Aegina. When he captured Aegina, in return for the favor, Sisyphus asked for a spring of water which he later named Pirene. This spring was situated near Corinth, and it represents not only a physical source of water but also the cleverness and resourcefulness that defined Sisyphus's character. The other choices do not relate directly to Sisyphus's story or the specific associations with any springs connected to him.
