What is consumer-to-consumer (C2C) e-commerce?

Consumer-to-consumer (C2C) e-commerce refers specifically to transactions where individuals sell goods or services directly to other individuals over the internet. This model facilitates peer-to-peer exchanges and is commonly seen on platforms like eBay, Craigslist, and various online marketplaces that enable personal sales and trades.

While options that refer to businesses selling directly to consumers or transactions between business entities describe other e-commerce models, they do not align with the definition of C2C e-commerce. Additionally, while online auctions for donated items might involve individual sellers and buyers, this description is too narrow and does not encompass the broader scope of all individual-to-individual sales, which is the essence of C2C e-commerce. Thus, the answer accurately represents the fundamental concept of C2C in the realm of e-commerce.
