Explanation:

The second one uses "te", which would be incorrect since we're talking about Graciela from a third-person point of view

The third uses says "el deporte", which is wrong because more than one sport was mentioned earlier, and "gustan" was used, which indicates more than one of the noun. You can't use "gustan" and a singular noun or "gusta" and a plural noun

The last is incorrect because even though it does say "gusta", once again, more than one sport was said

go here it should you! : )
