Actually, it is D for SQL Server. BUT! For SSAS u cannot revert to 1050, so you need to use a backup. So the question here is: what kind of database? What SQL Version?

Warning+
Setting the database compatibility to a higher level is irreversible. After you increase the compatibility level to 1100, you must continue to run the database on newer servers. You cannot rollback to 1050. You cannot attach or restore an 1100 database on a server version that is earlier than SQL Server 2012 or SQL Server 2017.
