B2C
B2C, or Business-to-Consumer, is a straightforward and direct business model where a company, such as company A, sells its products or services directly to individual consumers. 

In this model, the company interacts and transacts directly with the end users, without any intermediaries. This approach allows for a more personal and immediate connection with customers, enabling the company to tailor its marketing, sales, and customer service specifically to consumer preferences and needs.
