A . It is a model that is specified using UML diagrams.
B . It is a model that focuses on the domain requirements of the system
C . It is a model that captures the main domain concepts and their relationships.
D . It is a model that represents the domain architecture of the implementation of the system.

Answer: C

Explanation:

A domain model’s defining characteristic is that it captures the main domain concepts and their relationships. This model focuses on representing the key elements within the problem domain, outlining how these elements interact with each other without detailing the specific implementations. The domain model is an essential tool in software development for understanding and communicating the fundamental structure of the system from a problem domain perspective, helping teams to design solutions that are well-aligned with actual domain needs. UML is often used to represent domain models due to its capability to visually and clearly model complex relationships and structures.
