Hybrid cloud computing allows organizations to take advantage of public and private cloud models.

B (Encrypt data when it is at rest and in motion): In hybrid cloud deployments, encryption is one of the most critical mechanisms to protect sensitive enterprise data both during storage (at rest) and while being transmitted (in motion). This ensures confidentiality and integrity across both private and public cloud environments.

Other options explained:

A: Using standard protocols is a general best practice but insufficient without encryption.

C: Communication of risks is part of compliance but does not enforce technical security.

D: Using standard protocols without encryption exposes data to risks.
