Which statement is used to associate a submodule and a parent module in a YANG data model?

The import statement in YANG is used by a module to refer to definitions (e.g., types, groupings, data nodes) from other independent modules, not directly to associate a submodule with its parent.

The namespace statement defines the XML namespace for the data model defined by the module, serving as a unique identifier, not for associating submodules with parent modules.

In YANG data modeling, the include statement is used within a parent module to incorporate definitions from a submodule. This action makes all type definitions, groupings, and data nodes defined in the submodule available for use within the parent module, establishing the association.

The belongs-to statement is used within a submodule to explicitly declare which top-level module it is a part of, rather than being the statement in the parent module that pulls in the submodule's definitions.
