Final answer:
A copyright is a legal protection against copying original works of authorship, while a patent provides protection against both copying and independent creation of an invention. Copyrights last for the author's lifetime plus 70 years, and patents usually last for 20 years. Option A.
Step-by-step explanation:
The correct answer to the student's question is A. copyright, patent.
Copyright is a form of legal protection that prevents the unauthorized reproduction, display, or performance of original works of authorship, including books and music. It is intended to protect the creator's work from being copied for commercial purposes. Copyright lasts for the life of the author plus 70 years.
On the other hand, a patent is an intellectual property right granted to an inventor for a new and useful invention. It gives the patent holder the exclusive right to make, use, or sell the invention for a limited time, usually 20 years for new drugs, which prohibits not only copying but also independent creation of a patented product or process.
It is important to note that not every new idea is eligible for these protections. For instance, innovative business methods or training techniques typically cannot be protected with a patent or copyright.
So option A is correct.
