Got nothing to do with it. Computing wasn't invented in 1990.

Ctrl-c/v is a essentially a kludge introduced into Windows because the IBM Model M keyboard and similar didn't have a Meta key. It wasn't until Windows 3.1 that we see Ctrl-C and Ctrl-V being a 'thing'. Before then it was all about IBMs CUA. Apple had CMD-C/V/X on the Lisa 9 years before. I'm not sure what Xerox did on the Alto or if it even used keyboard shortcuts, but they did refer to the operation as Copy/Paste (coined by Larry Tesla who went on to work at Apple).

But on Unix and Linux pressing Ctrl-C in a terminal will send SIGINT (unless special measures are taken by your terminal emulator).

I think this another benefit of the Mac using Command-C for copy: when the UNIX-based Mac OS X was introduced you could copy from termainl windows without accidentally stopping the running program!

> Unix - Ctrl + c

Which Unix would that be? The closest thing to a common Unix desktop environment, the Common Desktop Environment, didn't steal Control because they had enough sense to know that people needed it to type control characters.

> Linux - Ctrl + c

The Linux desktop crowd has always been obsessed with cloning Windows.

Option-c types a ç character; the Mac doesn't (by default) use Option alone as a shortcut modifier key. You're thinking of Command.
