Explanation

Non-repudiation ensures that a party cannot later deny having performed an action, sent a message, or participated in a transaction. It is typically implemented via digital signatures and audit logs. For example, when a user digitally signs a document, the signature cryptographically binds them to that action - they cannot credibly repudiate (deny) it. The other options describe confidentiality, access control, and integrity - which are separate security principles.
