Tabletop full-fidelity trainers combine a physical tabletop setup, full-fidelity elements for realism, and instructional components for training. The question's individual options don't capture the entire concept, as all elements together form a TFT system.
The components of Tabletop full-fidelity trainers (TFT) typically include a physical tabletop setup that replicates a real-world environment or system, full-fidelity elements that provide a high level of detail and realism in the simulation, and trainers or instructional components that guide the user through the training scenarios. These systems are designed to offer users a realistic and immersive experience for training purposes in various fields such as aviation, military, emergency response, and medical training. The correct answer to the question is none of the individual options listed (1-3) completely describe the components of a TFT; instead, all these elements together make up a TFT system.
