Which option correctly names the leg carry trunk model?

• A. Leg carry trunk model
• B. Spine engine model
• C. Biotensegrity model
• D. Gel-Sol model

Answer: (A)

The main idea tested here is recognizing the specific name used for a particular biomechanical description of how the upper body is supported during movement. The term that exactly matches the described concept is the leg carry trunk model, since it literally names the arrangement where the trunk is carried by the legs as part of how posture and locomotion are organized. That precision in wording is why it’s the best choice. Other terms refer to broader or different frameworks. The spine engine model emphasizes the spine and its components as the driver of movement rather than a description of how the trunk is carried by the legs. Biotensegrity describes the body as a tensegrity structure with bones and soft tissues arranged in a continuous tension–compression system, which is a general structural concept rather than the specific leg-to-trunk carrying pattern. The gel-Sol model pertains to cytoplasmic flow and cytoskeletal dynamics at the cellular level, not whole-body posture models.
