Selected Answer: B
Creating separate Dockerfiles for each environment: * Violates the "build once, run anywhere" principle * Makes maintenance more difficult * Increases the risk of configuration drift * Requires rebuilding images for configuration changes * Goes against Docker best practices The better approaches for handling environment-specific configurations - Using Docker Configs and Secrets, Using Environment Variables, Using Docker Volumes.

B While technically possible, creating a separate Dockerfile for each environment is not the most efficient or scalable way to manage configurations that vary across environments.
