B Correct answer
Explanation

In Netezza HA (High Availability) architecture, each SPU (Snippet Processing Unit) has a mirror SPU located in a different SPA (Snippet Processor Array). This separation provides redundancy - if one SPA fails, the mirror in another SPA can serve requests. Putting both in the same SPA would defeat the purpose of HA.
