Consumers selling goods and services electronically to other consumers is best described as?

The term that best describes consumers selling goods and services electronically to other consumers is indeed C2C electronic commerce. This type of commerce involves transactions where individuals interact directly with one another to buy and sell products or services, typically facilitated through online platforms. Examples include auction sites and peer-to-peer selling platforms.

Disintermediation refers to the removal of intermediaries in a supply chain, which could apply to businesses but does not specifically describe consumer-to-consumer transactions. M-commerce refers to mobile commerce, the buying and selling of goods through mobile devices, which can occur within various commerce models but does not specifically denote the consumer-to-consumer paradigm. B2C electronic commerce stands for business-to-consumer transactions, where businesses sell directly to consumers, making it distinct from the consumer-focused transactions in C2C commerce. Therefore, the correct choice emphasizes the direct engagement of consumers with each other in an electronic marketplace.
