What container in AD holds deleted objects?

I am in HTB academy, I have started the topic of active directory and there is a question that does not give me as good, the question is the following “What container in AD holds deleted objects?”, I am putting that it is the AD recycle bin , but it does not give it to me as valid. Someone could help me to find out what is happening or to know if that question gives an error to the page or something

Simply because its not the good answer.

Check the hints and go back to read a bit more above AD recycle bin.

Hint is : It goes above a grave

Cheers !
