What platform can host Nova's Web app container image for distribution?

Docker Hub is the correct choice for hosting Nova's Web app container image for distribution. As a cloud-based registry service, Docker Hub allows users to store, share, and manage container images. By leveraging Docker Hub, developers can easily push their application images to the cloud, making them accessible from anywhere and allowing for simple integration into continuous deployment and delivery workflows. Other developers can also pull these images to deploy applications on their own systems.

The other options do not serve as hosting platforms for container images. The Docker client program is a command-line interface used to interact with Docker and manage containers, but it does not provide a means to host images itself. DockerProvider typically refers to a specific cloud or service provider that supports Docker containers, rather than being a hosting service. The Docker daemon is the background process that manages container creation and execution on a local machine, acting as the engine for running Docker containers but not as a hosting environment for image distribution.
