Explanation

Option B is correct because it reflects the logical flow of a real-world Docker deployment: you first develop the application and build the image locally (2), then push it to a registry so others can access it (5), pull it on the target machine (1), run a container from it (3), and finally verify the container is healthy (4). Option A fails because it begins with pulling an image that has not yet been created, making steps 1 and 5 logically impossible before step 2. Option C is nonsensical for the same reason -- you cannot upload or run an image before it has been built. Option D places the upload at the very end, after already running the container, which contradicts the purpose of a registry as a distribution point between build and deployment environments.

Memory tip: Follow the developer lifecycle -- Build it, Ship it, Get it, Use it, Check it (2-5-1-3-4). The registry always sits between the builder and the runner, so pushing must come before pulling.
