Final answer:
The hierarchical and network data models both depict a set of one-to-many relationships. The hierarchical model follows a strict tree-like structure, while the network model is more flexible with web-like connections.
Step-by-step explanation:
The data models that depict a set of one-to-many relationships are both hierarchical and network data models.
In a hierarchical model, data is organized into a tree-like structure that implies a single-parent to many-children relationship. Each parent can have multiple child records, but each child has only one parent, creating a one-to-many relationship hierarchy.
Similarly, the network model allows each child to have multiple parents, potentially forming a web-like structure of nodes and connections. Even though it's more flexible than the hierarchical model as it permits many-to-many relationships, the one-to-many relationship is a fundamental aspect of the network model where one parent can be linked to multiple child nodes.
Therefore, the answer to the question is "d.) both hierarchical and network" models.
