Hey there!
Question #1.
Reflexive pronouns are pronouns that reflect back on the verb committing the action.
For example:
She skipped and hurt herself.
In the sentence, it shows the verb (which is the action) before the pronoun.
Question #2:
Your answer is the last option: "ourselves".
This is because a reflexive pronoun is basically a word that ends with "self" or "selves".
Hope this helps you.
Have a great day!
