Final answer:
In Salesforce, a 'deployment' specifies the 'default' test coverage 'threshold' that applies to 'deployments'. This can be edited for a higher 'standard' to specific 'classes'.
Step-by-step explanation:
The minimum Apex test coverage you specify in the deployment will be the default test coverage threshold that will be applied to deployments originating in that environment. Therefore, the correct fill in the blanks would be: A) Pipeline / Default / Threshold / Deployments. However, you can edit this code coverage threshold and apply a higher standard to a particular class.
