All of the options provided are data models.

(a) Spatial Data Model: This is a type of data model that is used to structure geographic data. It is used in Geographic Information Systems and other applications that require spatial awareness.

(b) Network Data Model: This is a database model conceived as a flexible way of representing objects and their relationships. Its distinguishing feature is that the schema, viewed as a graph in which object types are nodes and relationship types are arcs, is not restricted to being a hierarchy or lattice.

(c) Temporal Data Model: This is a data model that is designed to track changes over time. It's used in fields like finance, where it's important to track changes to values over time.

(d) Hierarchical Data Model: This is a data model in which the data is organized into a tree-like structure. The structure allows representing information using parent/child relationships: each parent can have many children, but each child has only one parent.
