Ellen must correct sentence D) Odysseus, the main character, and his men meet many obstacles on there journey home from Troy to Ithaca.
Instead of "there", Ellen should write "their". "There" can be used as an adverb, an interjection, an adjective, and even as a noun, but it cannot be used as a possessive pronoun, which aims to show that something belongs to someone. The correct spelling for the possessive pronoun in order to refer to Odysseus and his men's journey is "their".
