The correct answer is C.
OBJ-3.4: Continuous deployment is a software development method in which app and platform updates are committed to production rapidly. Continuous delivery is a software development method in which app and platform requirements are frequently tested and validated for immediate availability. Continuous integration is a software development method in which code updates are tested and committed to development or build server/code repositories rapidly. Continuous monitoring is the technique of constantly evaluating an environment for changes so that new risks may be more quickly detected and business operations improved upon. While continuous deployment and continuous delivery sound very similar, there is one key difference. In continuous delivery, a human is still required to approve the release into the production environment. In continuous deployment, the test and release process into the production environment is automated, making the changes available for immediate release once the code is committed.
