Answer:
It is eras
Explanation:
Took the test, the answer is with eras, as it applies to "tu"
The correct sentence would be: ¿Ella es artística? (it looks kind of weird though because that's not commonly used).
The error is that you're talking in third person, but you used a first-person verb, therefore to fix it just change the verb from "soy" to "es".
Good luck!
