What is an example of B2C e-commerce?

B2C e-commerce, or Business-to-Consumer e-commerce, involves transactions where businesses sell products or services directly to consumers. The option that exemplifies this concept well is when a consumer purchases items online using a store credit card. This scenario highlights the transaction flow from the business, which provides the product, directly to the consumer who is buying it.

In B2C, businesses communicate with individual consumers through their websites or online platforms, facilitating ease of access for consumers to shop for goods and services. The use of a store credit card further indicates that this process takes place within an e-commerce framework, reinforcing the consumer's role in the transaction.

The other options illustrate different types of commerce. Trading items between consumers represents peer-to-peer interactions and does not involve a business. A business selling products to another business exemplifies B2B (Business-to-Business) e-commerce rather than B2C. Thus, the distinction in transaction types is what makes the selected option the best example of B2C e-commerce.
