Answer:
1. usted, él
2. vosotras, ellas
3. vosotros, ellos
Explanation:
Here you must say what is the appropriate personal pronoun according to the person.
To talk about "he" in Spanish, there are two options: "tú" and "usted". "tú" is informal and "usted" is formal.
"usted" is when you are talking with him, and "él" is for a man and when you are talking about him.
When you talk for two or more people, if they are women you say "vosotras" or "ellas", but if some of them are men you say "vosotros" or "ellos".
Vosotras and vosotros is when you are talking with them, and "ellas" o "ellos" is when you are talking about them.
