Answer: Compare the canary with the existing deployment of the current production version.

The application's in-memory cache loads objects at startup, meaning the production version has a 'warm' cache after running, while a newly deployed instance would start with a 'cold' cache. Canary analysis must compare the canary (new version) against the actual production environment to accurately assess performance. Option A or B would deploy a fresh instance with a cold cache, skewing results. Option D relies on historical averages, which may not reflect current conditions. Option C compares the canary directly to the existing production deployment, which has a warm cache and real-time traffic, providing the most accurate baseline for automated analysis.
