Concept:The key point is that a patent grants an inventor exclusive control over the production and sale of a specific invention, while a trademark protects brand identifiers.
Explanation:A patent gives the owner the legal right to exclude others from making, using, or selling an invention for a limited period.
This exclusive control over a product creates a monopoly because the patent holder is the only one allowed to commercially exploit that invention.
A trademark, on the other hand, protects names, logos, and symbols that distinguish goods or services from competitors.
The difference in the question is about what the latter right, i.e., a patent, confers.
A patent confers a monopoly on a particular product or invention.
Answer:Option C: confers monopoly on a product.
