B选项是啥意思

问题如下：

The business model that involves a company facilitating contributions directly from its users to online content is best described as:

选项：

A.

Marketplace business model.

B.

Platform business model.

C.

Crowdsourcing business model.

解释：

C is correct because crowdsourcing enables a business to obtain input, content, or ideas from a broad user base rather than relying solely on in-house resources. This model is characterized by the company setting up a framework or platform for contributions, which it then oversees with minimal moderation. Common applications of crowdsourcing include social media, product reviews, open-source software development, and knowledge aggregation platforms like Wikis​​.

A is incorrect as a marketplace business model primarily connects buyers and sellers within a platform without directly involving the creation of content by its users.

B is incorrect because while a platform business model can facilitate interactions among different user groups, it does not specifically describe a model where users contribute directly to the content or services offered by the company.
