Answer: B,C
Explanation:
https://docs.cloud.oracle.com/en-us/iaas/Content/Database/Concepts/databaseoverview.htm License Types and Bring Your Own License (BYOL) Availability Oracle Cloud Infrastructure supports a licensing model with two license types. With License included, the cost of the cloud service includes a license for the Database service. With Bring Your Own License (BYOL), Oracle Database customers can use existing licenses with Oracle Cloud Infrastructure. Note that Oracle Database customers remain responsible for complying with license restrictions applicable to their BYOL licenses, as defined in their program order for those licenses.
You do not need separate on-premises licenses and cloud licenses. BYOL databases support all advanced Database service manageability functionality, including backing up and restoring a DB system, patching, and Oracle Data Guard.
You can choose BYOL when you launch an Oracle Cloud Infrastructure database or DB system. Choosing BYOL impacts how the usage data for the instance is metered and subsequent billing.
Note that on some provisioning dialogs in the Console, the BYOL option is labeled My Organization Already Owns Oracle Database Software Licenses.
