Bis correct: the OCI’s main purpose is to createopen, vendor-neutral industry standardsforcontainer image formatsandcontainer runtimes. Standardization is critical in container orchestration because portability is a core promise: you should be able to build an image once and run it across different environments and runtimes without rewriting packaging or execution logic.
OCI defines (at a high level) two foundational specs:
Image specification: how container images are packaged (layers, metadata, manifests).
Runtime specification: how to run a container (filesystem setup, namespaces/cgroups behavior, lifecycle).These standards enable interoperability across tooling. For example, higher-level runtimes (like containerd or CRI-O) rely on OCI-compliant components (often runc or equivalents) to execute containers consistently.
Why the other options are not the best answer:
A(accelerating adoption) might be an indirect outcome, but it’s not the OCI’s core charter.
Cis contradictory (“industry standards” but “for private purposes”)—OCI is explicitly about open standards.
D(improving security) can be helped by standardization and best practices, but OCI is not primarily a security standards body; its central function isformat and runtime interoperability.
In Kubernetes specifically, OCI is part of the “plumbing” that makes runtimes replaceable. Kubernetes talks to runtimes via CRI; runtimes execute containers via OCI. This layering helps Kubernetes remain runtime-agnostic while still benefiting from consistent container behavior everywhere.
Therefore, the correct choice isB: OCI creates open standards around container formats and runtimes.
