A large customer is consolidating their pSeries systems onto a p5 590. They will have a requirement for a single device (disk, lun) to have multiple paths through different  adapters in a single LPAR. The primary applications were written for AIX 5.2. Which of the following would be the recommended solution to satisfy this requirement?（）

• A、Assign the adapters to a Virtual IO partition
• B、Use the MPIO function included in AIX 5.2
• C、Migrate the application to AIX 5.3 and use the MPIO function
• D、Set up two Virtual IO partitions and attach both partitions to the device
