Continuous deployment is distinct from continuous delivery because it automatically moves validated changes into the live production environment. That is why option C is correct. In continuous delivery, changes are integrated, tested, and made ready for release, but a deliberate business or operational decision may still be required before deployment to production. In continuous deployment, that final manual release decision is removed, and successful changes flow directly into use. This requires strong automation, testing discipline, monitoring, and confidence in the deployment pipeline. Option B is incorrect because continuous delivery does not require manual code integration; integration is normally frequent and automated. Option D is also wrong because testing becomes more important, not less. ITIL aligns these practices with modern value stream optimization and reliable change flow.
