单项选择题You have created a resource plan， PROD_DB_PLAN， that uses the RATIO policy. The following consumer groups and their respective plan directives have been assigned to this resource plan： Consumer group HIGH_CG with CPU_P1 as 10.  Consumer group MEDIUM_CG with CPU_P1 as 5.  Consumer group LOW_CG with CPU_P1 as 2.  Consumer group OTHER_GROUPS with CPU_P1 as 1.  Which statement is correct in this scenario？（）

A.The plan PROD_DB_PLAN can have subplans.
B.The members of the HIGH_CG consumer group would get 10% of the CPU.
C.The CPU allocation for the consumer groups would be based on the ratio defined for the CPU_P1.
D.The CPU allocation would be equal between the HIGH_CG and MEDIUM_CG consumer groups if there are no sessions existing for the LOW_CG and OTHER_GROUPS consumer groups.
