Answer:
D. Patent
Explanation:
Patent is the intellectual property right that protects inventions, innovations, and discoveries. Once a patent is registered, the law gives the owner exclusive rights to commercial benefits from their invention for a limited time, usually 20 years. The patent is essentially a monopoly granted by the law. It prevents others from duplicating and profiting from the ideas of the patent holder.
Patents protect inventions while copyrights safeguard artists' creations. Authors, musicians, paint artists, movie-makers, software developers all use copyrights to protect their original works. Trademarks protect brand names.
