Non-repudiation means you can't deny sending a message.

I’m a bit confused because I thought non-repudiation also had something to do with data access. But I guess that’s more about option B, right?

I practiced a similar question last week, and I think non-repudiation specifically deals with accountability in communications. So, I’d go with C.

I remember studying this, but I’m not completely sure. It seems like it could relate to data integrity too, but that might be more about option D.

I think non-repudiation is about ensuring that the sender can't deny sending a message. So, I’m leaning towards option C.
