According to the passage, which of the following statements is INCORRECT ( )

参考解析：

A项，在线文凭将补充传统学位的作用，B项，大学正在参与在线课程的设计和交付，C项，雇主接受网上证书是因为他们有创新精神，D项，需要标准来弥补在线程序之间的质量差距。最后一段new types of online credentials — various certificates, MicroMasters, badges, and the like — are instead playing a complementary role, creating the building blocks for newer, more affordable degree programs. This represents true innovation in terms of the fundamental cost inputs (including faculty labor), pricing, and service expectations associated with the delivery of degrees. 表明A正确B错误，只是说到了基本成本投入、定价和学位交付预期创新，没有说到大学生正在加入网络课程的交付。故本题正确答案选B。
