How to reset security questions in icloud?

Question

Apple iCloud

Good evening, today I was digging in iCloud, and I was asked to answer security questions, but I don’t remember them, for the life of me, I can’t quit them, because I need to answer them ...
I also can’t reset them for a reason, since there is no backup mail, and I can’t add it, because it requires answering these questions ... What should I do? Help!
