Explanation

Encryption at rest protects data that is stored (not moving). Encrypting a virtual machine disk (B) is a classic example - the data is encrypted while sitting on storage media using Azure Disk Encryption or server-side encryption. A site-to-site VPN (A) and HTTPS (C) are examples of encryption in transit, protecting data as it moves over a network. Sending an encrypted email (D) is also encryption in transit/use, not at rest.
