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.

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.
