Answer: C

The "Trademark Law" stipulates that if a natural person, legal person or other organization needs to obtain the exclusive right to use a trademark for its goods or services in production and business activities, it must submit a request to the Trademark Office Apply for trademark registration. Products that require the use of registered trademarks under laws and administrative regulations must apply for trademark registration. Products without approved registration may not be sold in the market. The "Tobacco Monopoly Law of the People's Republic of China" (hereinafter referred to as the "Tobacco Monopoly Law") stipulates that cigarettes, cigars and packaged cut tobacco must apply for trademark registration. Without approval and registration, they shall not be produced or sold. Therefore, option C is correct.
