The correct answer is B, as it describes a textual model, which primarily relies on natural language to convey information. Textual models articulate concepts, processes, and relationships through written descriptions, definitions, and narratives. This approach helps to clarify ideas without the need for visual elements or numerical data, making it particularly effective for communicating complex theories and frameworks in a more digestible format.

Textual models serve as foundational tools in various disciplines, enabling engineers and other professionals to document, share, and discuss their thoughts systematically. For instance, in engineering, specifications, requirements, and design documents often utilize textual models to ensure clarity and precision among teams.

In contrast, other types of models like graphical, mathematical, and physical use different mediums. Graphical models rely on visuals like diagrams or charts to represent data or processes. Mathematical models use equations to express relationships quantitatively. Physical models involve tangible representations of systems or structures, which can be physically manipulated or observed. Each of these models plays a distinct role in the communication and understanding of engineering concepts, but only textual models focus solely on verbal and written representations.
