Containers access an operating system is option B:containers use a shared base operating system stored in a shared runtime layer.

The host OS is shared by all containers, so they are not required to boot an OS or load libraries. This makes containers much lighter and more efficient. Applications that are containerized can start quickly, and compared to VM scenarios, many more instances of the application can be installed on the machine.

Note that without the traditional need for virtual machines, containers can share access to an OS kernel. Partitioning from the 1960s and chroot process isolation from Unix in the 1970s are the foundations of container technology.

Hence, Operating system virtualization is a technique used with containers. From a small software process or microservice to a more complex application, anything can be run inside of a single container.
