Which statement about containers is correct?

Containerization abstracts hardware resources, allowing applications to run in isolated environments without the need for a full operating system for each application. This abstraction enables developers to package applications and their dependencies together, creating a uniform environment for software to execute across different computing environments. This is especially beneficial for deployment consistency and scalability, as containers can be easily moved between development, testing, and production environments.

By contrast, the other statements contain inaccuracies regarding the capabilities and characteristics of containers. While containers can host both stateful and stateless applications, the notion that they can only run stateless applications is overly limiting. Additionally, containers are generally more lightweight compared to virtual machines, usually utilizing fewer resources because they share the host system's operating system kernel instead of requiring a separate OS for each instance. Hence, characterizing them as inherently resource-intensive does not accurately portray their efficiency and design principles.
