Cloud storage in education – UGC NET Question

Statements B, C and D correctly describe typical features of educational cloud storage services, while A is false. Cloud storage is designed to be accessed from multiple authorised devices over the Internet, not restricted to one device. Many services also maintain version history and support shared folders for collaboration. Therefore, the combination B, C and D only is the correct set of statements.

Option A:
Option A is incomplete because it includes only B and C and omits D. While remote storage and version history are important, shared folders for collaborative work are also a central reason institutions adopt cloud storage.

Option B:
Option B is correct because it gathers all three true statements and excludes A, which wrongly claims that access is limited to a single device. It accurately reflects how cloud storage is used for flexible and collaborative educational work.

Option C:
Option C is incorrect because it includes A, B and C as correct and thus accepts A. Since cloud services are typically available across multiple devices, accepting A contradicts the common design of such systems.

Option D:
Option D is incorrect because it assumes that all four statements are correct and therefore accepts the false restriction described in A. This combination misrepresents the multi-device accessibility of cloud storage.
