A Correct answer
Explanation

PGP (Pretty Good Privacy) was created by Phil Zimmermann in 1991, not 1992. It has been available as freeware since its inception. The IETF (Internet Engineering Task Force) standardized OpenPGP (RFC 4880) but doesn't 'regulate' PGP. While PGP uses similar cryptographic concepts to PEM (Privacy Enhanced Mail), they use different algorithms and formats.
