Explanation

docker build is the standard command for building a container image from a Dockerfile - it's been the core Docker CLI command for this purpose since Docker's early days and remains the canonical way to create images.

Why the distractors are wrong:

• A. docker image create - This command doesn't exist; the closest real command is docker image build, which is an alias for docker build.
• B. oci build - There is no standard oci CLI tool with a build subcommand; OCI (Open Container Initiative) is a specification, not a CLI.
• D. tanzu build - Tanzu is VMware's application platform; it's unrelated to building standard container images directly.

Memory tip: Think of it as a construction analogy - you're a Docker contractor, and you build the container. The syntax mirrors common sense: docker build . tells Docker to build an image from the current directory's Dockerfile.
