Answer: C

Explanation:

Containerization (e.g., using Docker) helps configuration management by encapsulating an application and all its dependencies, libraries, and environment settings into a single container. This ensures that the application runs the same way regardless of where it is deployed—development, staging, or production. It solves the “it works on my machine” problem and simplifies CD by eliminating inconsistencies in environment configurations. Containers also make it easier to test, scale, and rollback applications. This packaging approach supports faster deployment, better resource utilization, and smoother configuration management.
