Step-by-step explanation:
The type of e-commerce that allows anyone to sell or trade items online is C2C e-commerce (3)(Consumer-to-Consumer). In a C2C e-commerce environment, both buyers and sellers are individuals, not businesses. This setting is typically represented by online platforms like eBay, Craigslist, or Etsy, where individuals can list their products or services for others to purchase. Participation in these markets has been greatly facilitated by advancements in technology and globalization, which have made it easier for people from all over the world to engage in transactions with one another. The key features of C2C markets include many sellers offering identical or similar products, sellers and buyers being well-informed about products, and easy market entry and exit for sellers.
