B “As models are more formal, they offer a higher degree of uniqueness compared to natural language.” Models use defined notation and semantics, so they are less ambiguous than free text. C “In requirements engineering models are more suitable than textual descriptions to reduce the complexity of the entity being considered.” Diagrams let stakeholders grasp structure and behaviour at a glance, helping to manage complexity.
