Which daughter of Ceres was abducted by Pluto to be his wife?

The correct answer is Proserpina. In Roman mythology, Proserpina is the daughter of Ceres, the goddess of agriculture, grain, and the harvest. Her story is well-known and significant within the myths, primarily due to her abduction by Pluto, the god of the underworld. This event is a central theme in the mythology surrounding the changing seasons; when Proserpina is taken to the underworld, her mother mourns her absence, resulting in the barren winter months. This seasonal cycle illustrates the connection between the changing seasons and the myth of Proserpina's dual existence in both the living world and the underworld.

While Persephone is the Greek name for the same goddess and often associated with her abduction story, the question specifically refers to the Roman version, which is Proserpina. The other figures mentioned, such as Ariadne and Andromeda, are prominent in other mythological narratives but do not share the same connection to Ceres or the story of abduction by Pluto. Ariadne is known for her involvement with Theseus and the Minotaur, while Andromeda is most famously linked to her encounter with Perseus and the sea monster.
