Which best describes business growth that attracts more customers and merchants, contributing to further growth in the business?
选项：
A.Crowdsourcing
B.A one-sided network
C.A multi-sided network
解释：
Correct Answer: C
C is correct because as multi-sided [two-sided] networks grow—more users join the service, which attracts more merchants, which in turn attracts more users—these businesses can grow exponentially.
A is incorrect because crowdsourcing is where users contribute directly to a product or service. These businesses facilitate “user communities” that enable voluntary collaboration between users of a product with a small amount of moderation and oversight by the company.
B is incorrect because a one-sided network is one where it is only one type of user that is valuable to other users.
B和C的区别是？为什么不选单边。。。
