Companycom is currently using a p690 and has just ordered a p5 590. They prefer to run in full system partition mode, since their application will utilize all the resources in the machine, and they don't want the overhead of an LPAR. What is the best response to the customer about the POWER5 capabilities?（）

• A、POWER5 runs in an SMP mode as default
• B、POWER5 can run in a full system mode the same as the p690
• C、POWER5 can run in full system mode with the purchase of PLM
• D、POWER5 can run in a full system mode， but it is in LPAR mode
