How Reactivate facebook accounts

I have had these 9 Facebook accounts for over 2 years.

However I did not use them for posting for the past 1.5 years. The accounts do not have any friends because I do not want to verify any faces through Facebook security. I use the accounts for posting in groups alone.

I wanted to login yesterday and I discovered all the accounts were prompting some security. Only that the security question is not coming up and I couldn't proceed from this window

Please assist, how can revive these accounts in order to use them for posting again like before

If you haven't been using them for quite some time now, just abandon the accounts and create new ones. It's time-consuming to go through verification. Set up new email accounts for your new fake accounts, instead, then use fake mobile numbers if it prompts for such. -Micah
