If I had to choose one, I would choose A.
This topic is not good.
Reasons for choosing A: Broadly speaking, trademarks can be divided into product trademarks and service trademarks. According to China's current international classification table, 1-35 is a product trademark; Categories 35-45 are service marks.
Underwear belongs to clothing, that is, 25 kinds of products, and sales agents belong to 35 kinds of services. However, the State Trademark Office answered whether supermarkets and specialty stores can register a sales service trademark in the 35th category and get protection: the 35th category does not include supermarkets, specialty stores and shops. In other words, in China, these units (such as Gome, which does not produce products) must register trademarks in the product categories to be protected.
This topic is unprofessional, and it must be someone who has a little knowledge of "intellectual property rights".
From the questioner's point of view, a is chosen because it is relative to the product trademark; A sales trademark is also a service trademark.
(Intellectual property mainly refers to copyright, trademark right, patent right, etc. )
I hope my answer can solve your problem and help you. Have a happy day!
