What is the purpose of the version field in AddressHistory?

• A. Tracks different versions over time
• B. Indicates encryption level
• C. Stores the last login date
• D. Flags if address is active

Answer: (A)

Tracking the evolution of an address over time is what the version field does. Each change to an address creates a new version, preserving the exact state for that moment so you can see what the address looked like at any point and support auditing or rollback if needed. Encryption level, last login date, and an active flag serve other purposes and do not represent historical states. So the version field is about maintaining multiple snapshots of an address as it changes.
