Final answer:
The default assignment of an asset type is typically inherited from the parent asset type in the system, providing consistency and efficiency in asset management.
Step-by-step explanation:
By default, the assignment of an asset type typically comes from the hierarchical structure of the asset management system being used. This usually means that the assignment of an asset type is inherited from the parent asset type (option c). The inheritance mechanism ensures consistency and streamlines the process for managing assets across an organization or within a system. When you create a new asset, it will often have predefined attributes and settings derived from its parent asset type, which dictates the default values for those assets within that category.
