b) is there a port (or distribution) of GnuPG
Not that I know of.
Details: There are probably technical and license challenges to port
GnuPG to iOS. While I believe that it is possible to port C applications
to iOS, it is unclear if someone could place it is in the appstore.
Note that GnuPG ports to MacOSX exist.
c) Are there compatible OpenPGP and OpenPGP/MIME implementations for
Yes, e.g. Openkeychain + K9Mail (both being Free Software)
d) Are there compatible OpenPGP and OpenPGP/MIME implementations for iOS?
Yes, though proprietary Software (AFAIK), for example I've heard about
Canary Mail, iPGMail, PGPro, Safe Easy Privacy

PGPro is open source, but neither it nor iPGMail handle openPGP/MIME -
they use various tricks with the clipboard and attachments to exchange
ciphertext with the native iOS mail app, due to restrictions in iOS
<=v13 that forbid third-party apps direct access to the mail delivery API.
(The less said about SAFE Easy Privacy's hateful UX, the better)
Canary Mail is the only one of the above which has (so far) taken
advantage of the new iOS 14 app policy to implement openPGP/MIME. I have
not used it much, but it appears well-built (and closed-source, and pricey).
