Which of the following is an example of Consumer to Consumer eCommerce?

The correct answer highlights a scenario where individuals engage directly with each other to buy, sell, or trade, which is the essence of Consumer to Consumer (C2C) eCommerce. In this context, trading items on social media marketplaces allows users to connect and facilitate transactions among themselves without the involvement of traditional retailers or businesses, thus embodying the C2C model.

C2C eCommerce is characterized by its reliance on user-generated content and social interaction, often facilitated by platforms that provide a space for individuals to list items, negotiate, and complete purchases directly between themselves. This model is increasingly popular as it fosters community-based trading and a peer-driven marketplace.

In contrast, other options illustrate different eCommerce models. Purchasing goods from an online store falls into the Business to Consumer (B2C) category, where businesses sell directly to consumers. Companies selling services to other businesses is classified as Business to Business (B2B) eCommerce. Advertisers targeting consumers through online ads also do not fit the C2C model, as this pertains to marketing strategies rather than direct consumer transactions. Thus, the choice focused on trading items on social media marketplaces distinctly aligns with the principles of C2C eCommerce.
