Step-by-step explanation:
The correct answer is a. 6 to 10 years.
Trademarks are a form of intellectual property rights that protect brand names, logos, and symbols. In the context of drugs, a trademarked drug refers to a drug that has a unique brand name that is protected from other people manufacturing it.
Unlike patents, which protect the invention itself, trademarks protect the branding and identity of a product. Trademarks are typically protected for a period of 6 to 10 years, although this can vary depending on the country.
