Complete following sentence: In the generic metamodel the main types of elements can be divided into

The ArchiMate generic metamodel provides a high-level classification for all elements. The primary division is between structure elements and behavior elements. Structure elements are further divided into active structure (the "subjects" that perform behavior) and passive structure (the "objects" on which behavior is performed). Behavior elements represent the "verbs" or actions. Therefore, the main types are structure and behavior.

A. resources and events: These are specific types of passive structure and behavior elements, respectively, not the main categories of the metamodel.
C. grouping and location: These are auxiliary elements used for organizing or locating other elements, not the primary classification types.
D. process and function: Both are specific types of behavior elements, representing an incomplete classification of the metamodel.
