When is an original work considered public domain?

Computers and Technology
1 answer:
Blababa [14]3 years ago
7 0

The correct answer isn’t really a choice shown. I would choose D because if a work doesn’t have a copyright symbol that doesn’t mean it’s in the public domain. In a real life situation it would be best to ask the creator before you use their work. If they say it’s in the public domain then you’re fine, but even if they say you can use it that doesn’t mean it’s in the public domain, it just means that you have permission to use it.
