The correct verbs that agree with the subject "everyone" are is and agrees.
"Everyone" is treated as a singular noun in terms of verb agreement. Therefore, you would say "Everyone is here" or "Everyone agrees."
So from your list, the correct choices are:
- is
- agrees (though "agree" is not listed; if "agree" is meant to be considered, then it's not correct with "everyone")
From your provided options, the only verb that matches is "is." The verb "agree" does not correctly match the singular subject "everyone."
