Universal Containers have changes that need to be deployed from Sandbox to Production.

The correct place to verify whether a change set can be deployed is Inbound Change Sets in the target org, normally Production.

Salesforce guidance says that after uploading a change set from the source sandbox, the app builder goes to Setup → Inbound Change Sets, opens the change set awaiting deployment, and clicks Validate. Validation checks whether the deployment succeeds or fails before committing the changes.

A. Deployment Settings is mainly used to authorize deployment connections and allow inbound changes from another org. C. Deployment Status is used to monitor deployment progress/results, not to initiate validation of an inbound change set.
