    Answer: D


    Explanation: Monolithic testing is not a common approach for testing microservices in a cloud-native Java application. Monolithic testing typically refers to testing a monolithic application as a whole, rather than individual microservices. In a cloud-native architecture, where applications are composed of loosely coupled microservices, testing is typically focused on individual microservices and their interactions.
