  - Correct answer : A — `client.delete_registered_model_tag(name="pricing_model", key="status")` to remove the key from the registered model. A . `delete_registered_model_tag` removes the key entirely from the registered model's tag set, which matches the requirement to drop the `status` key rather than merely blank out its value. B . Setting the value to an empty string still leaves the `status` key present with an empty value, so it would still show up in tag listings and tag-based searches instead of disappearing. C . This targets a tag on a specific model version rather than the registered model, so it would not touch the model-level `status` tag the team wants removed. D . Unity Catalog's Model Registry does not use the legacy workspace-registry stage concept, and even if a stage transition existed here, changing a version's stage would not delete a tag on the registered model.
