To determine the correct answer to the question, let's analyze the options provided:

1. **Linguistic models**: These models are generally centered around the understanding and processing of language, and they do not specifically represent tasks or goals related to user tasks.

2. **Physical and device models**: These models focus on the physical aspects of devices and their interaction with users, rather than the structure of user tasks and goals.

3. **Hierarchical models**: Hierarchical models organize tasks or goals in a structured manner, often visualized in a tree-like format. They effectively represent user tasks and their goals.

4. **None of the mentioned**: This option suggests that none of the provided choices are suitable, but based on the analysis, this is not true.

### Final Answer
**c. Hierarchical models** represent a task of the user and the structure of the goal.
