Which one is not the feature of the Huawei digital classroom solution?

In the Huawei Digital Classroom Solution , the "not correct" feature is Option A .

The Reality: While the solution includes a Digital Blackboard (an electronic companion to the IdeaHub) that supports chalk and synchronization, a standard "Green-colored blackboard" is an analog surface. If a teacher uses only chalks on a traditional green board, there is no electronic sensor to capture and synchronize that data to the IdeaHub. Synchronization requires the Electronic Blackboard hardware. Options B, C, and D are all core features highlighting the interactive and digitizing capabilities of the smart classroom environment.
