The correct choice is the State model because it specifically focuses on depicting the various states that an entity, such as a customer order, can progress through over its lifecycle. In this context, a State model allows a business analyst to illustrate the different statuses that an order might have, such as "open", "in process", "shipped", and "delivered".

By using a State model, the analyst can effectively communicate how the order transitions from one state to another based on events or actions, which is critical for understanding the workflow and for the design of related systems. This approach helps stakeholders visualize the dynamic aspects of the order system, including entry and exit criteria for each state, contributing significantly to the clarity of requirements.

Other models, such as Class models, focus on the characteristics and behaviors of entities rather than their states. An Entity-Relationship model primarily addresses the relationships and associations between different entities, while an Attribute model does not depict states at all; it only details the properties or characteristics of an entity. Therefore, when illustrating the lifecycle changes or statuses of an order, the State model is the most appropriate choice.
