Answer: D

Explanation:

In UML, a template is a parameterizable element, and the parameters for a template are typically classes or other classifiers. According to the UML 2.x Superstructure Specification, all subclasses of Classifier can potentially be used as template parameters. This includes classes, components, datatypes, interfaces, signals, and more. The specification provides the flexibility to define template parameters that are specialized types, allowing for powerful and reusable designs. The ability to parameterize these elements is foundational to creating generic and reusable model elements, which is a core capability of the UML’s templating mechanism.
