单项选择题

You recently created a complex resource plan named DB_PLAN that has two subplans named OLTP_PLAN and DSS_PLAN. The OLTP_PLAN and DSS_PLAN subplans are allotted 70 percent and 30 percent of the total CPU resources， respectively. The OLTP_PLAN subplan allocates 35 percent of the available CPU resources to a resource consumer group named ACCT_CLERKS. According to the OLTP_PLAN subplan， the remaining 65 percent of the available CPU resources is allocated to a second resource consumer group named MKT_CLERKS. The CPU resources available to the DSS_PLAN subplan are divided into two resource consumer groups named MKT_MANAGERS and FIN_MANAGERS. The MKT_MANAGERS group receives 65 percent of the available CPU resources， and the FIN_MANAGERS group receives 35 percent of the available CPU resources. What percentage of actual CPU resources will the resource consumer group， MKT_CLERKS， receive， if the DSS_PLAN subplan does NOT consume any CPU resources？（）

A. 45.5
B. 65
C. 70
D. 100
