Containerization? That seems unrelated to model evaluation.

Containerization feels like it’s more about the environment rather than the model itself, so I’m leaning towards performance monitoring.

CI/CD sounds familiar, but I can't recall if it's specifically for model replacement or more for deployment processes.

I'm going with B. Gotta keep a close eye on those metrics, you know? Don't want to end up with a model that's worse than the one it's replacing.
