Why each option
Non-repudiation is a security principle that guarantees the sender of a message cannot later deny having sent it, providing undeniable proof of origin.
PKI (Public Key Infrastructure) is a framework that enables non-repudiation but is not the concept itself.
Verification is the act of confirming something is true, but it's not the specific term for preventing denial of sending.
Non-repudiation provides irrefutable proof of origin of data and its integrity, preventing a party from successfully denying the authenticity of their signature on a document or the sending of a message. This is often achieved through digital signatures and cryptographic techniques.
Irrevocable Trust is a general concept that doesn't specifically define the inability to deny an electronic transmission in a security context.
A Public Key is a component of PKI used in cryptography, but not the term for preventing denial of sending.
