What execution implementation fits these requirements?

A company wants to use ODM for asynchronous processing with large payloads and very strict performance guidelines. They want to keep data extraction and execution close to reduce any latency effects. They also need ODM to scale as they might want to execute rules from several different applications concurrently.

What execution implementation fits these requirements?
A . A stand-alone POJO session on a single V
C . A custom MDB with a stateful or stateless rule session.
D . A J2SE rule session to create a tightly coupled application with performance gains.
E . An HTDS web service and increase the size of the connection pool based on performance testing needs.

Answer: B
