Answer:
The correct answer is d. C2B
Step-by-step explanation:
It is a business model in which consumers (individuals) create value and commercial companies consume that value. For example, when a consumer writes reviews or when he gives a useful idea for the development of a new product; Then the consumer is creating value for the entrepreneur if the business adopts that idea or input. The concepts of crowd sourcing (tasks performed by a multitude of people) and co-creation are excepted here.
The C2B model, also called reverse auction or demand collection model, enables buyers to name or claim their own price, which is often linked to a particular good or service. The website collects the offers of the demand and then offers those offers to the participating sellers or companies.
