Answer: E. The data is not under the owner’s direct control.
Step-by-step explanation:
A massive disadvantage to cloud storage is that the data stored is ot under the direct control of the person uploading. They first have to access the service and that service is owned by the company offering the cloud storage.
If for any reason the company decides not to give access (depending on local laws), or if the company suffers a problem that affects its ability to offer the service, the person who uploaded could lose access to their data.
