Why each option

By default, all Azure Managed Disks, including OS and data disks, are encrypted at rest using server-side encryption with platform-managed keys.

ABoth of the disks are unencrypted.
BBoth of the disks are encrypted using server-side encryption.Correct

Server-side encryption is automatically enabled for all new Azure Managed Disks, providing encryption at rest without requiring any user configuration or a Key Vault for platform-managed keys.

CThe operating system disk is encrypted using server-side encryption. The data disk is unencrypted.
DThe Data disk is encrypted using server-side encryption. The operating system disk is unencrypted.

Both OS and data disks utilize server-side encryption by default, not just the data disk.
