Correct! Triptolemus is the "Johnny Appleseed" character whose magic chariot wound up being transformed into a tractor on a Greek postage stamp honoring Demeter. Since Triptolemus was honored by the goddess and accomplished his divine mission, his story certainly has a happier ending than the story of poor Demophoön, who according to most accounts simply pined away after he lost his divine nurse. Well, happier for Triptolemus himself if not for his family. In the alternative account, it's Triptolemus's father who discovers Demeter shoving the baby into the fire, and Demeter strikes his hapless Dad dead for presuming to spy on her activities.

While Triptolemus doesn't exactly become a god, he doesn't die a mortal death either. According to some accounts he was placed among the stars, and according to Plato's Apology 41a he is now honored as a judge of the recently deceased in the underworld.

Okay, I admit this has very little to do with Asclepius. It's kind of a trick question, to see if you'd choose "Asclepius." Just yanking your chain a little there.
