" Everyone" and the suitable question tag

[nour]

Hi everybody,
can anyone help me in this, I have been searching the web but I didn't find a suitable answer to my question.
Everyone, everybody, are indefinte pronouns so we use singular verbs as:

Everyone is at home.

:-?My question is : How can we form a question tag for this sentence:
Everyone is at home, isn't they?
OR
Everyone is at home, aren't they?


please can u help me with this as soon as possible.

Thanks.

Everyone is at home, aren't they? is correct.

'everyone' is singular, and takes the singular verb 'is'. 'they' is plural and so takes the plural verb.
What is implied by 'everyone' , (that is, 'every one of them is'), is that 'they are all at home'
He: Is everyone here?
She: They are.
