When assigning geography in SAD, which pairing is correct?

• A. CSA name : CSA number
• B. ZIP code : CSA name
• C. CSA number : CSA name
• D. Region : district

Answer: (C)

In SAD, the right approach is to map the identifying code to its human-readable label. The CSA number is the official identifier for a CSA, and the CSA name is the descriptive label that goes with it. Pairing the code with the name creates a stable, machine-friendly reference you can look up to display the correct, readable geography. This makes data joins and lookups reliable, since you always start from the unique code and translate it to the familiar name. Swapping them would make lookups awkward (mapping a name back to a code), mixing ZIP codes with CSA data uses different geographic systems, and pairing broader terms like region and district doesn't give you the precise, one-to-one CSA mapping that the system expects.
