Answer:
The word that best completes the phrase is:
- Sus padres están divorciados.
Explanation:
For a substantive in plural form, in this case "sus padres", the correct Perfect Form for "divorciado" with the personal pronouns is:
1. Yo estoy divorciado.
2. Tú estás divorciado.
3. Él está divorciado.
4. Ella está divorciada.
5. Ello está divorciado.
6. Nosotros estamos divorciados.
7. Ellos están divorciados.
How "los padres" could be replaced by the personal pronoun "ellos", the correct word is "divorciados", the other options don't apply because they are in singular form or don't have sense in the sentence.
