vCenter Server Appliance Database Requirements
Each vCenter Server Appliance instance must have its own database. You can use the bundled PostgreSQL database that is included in the vCenter Server Appliance, which supports up to 1,000 hosts and 10,000 virtual machines.
For external databases, the vCenter Server Appliance supports only Oracle databases.
A & B are correct. DB2 is not supported & MS SQL is only supported in a Windows base vCenter.
