Which signaling scenario is described as requiring holographic signaling as not permitted?

• A. Pre-recorded
• B. Holographic
• C. Synthesized
• D. Live

Answer: (B)

In this signaling framework, the method used to convey a message depends on the context of the scenario. Holographic signaling relies on a three‑dimensional display, which can introduce readability and accessibility issues in hazardous environments and often isn’t allowed under certain rules or conditions. When a scenario is described as holographic, the regulations for that scenario state that holographic signaling itself is not permitted. The message then must be delivered by other means—pre-recorded, synthesized, or live announcements—rather than by holographic displays. The other options represent alternative signaling methods that could be used in different contexts, but they describe modalities that are not the restricted one in this holographic scenario. Therefore, the scenario that describes holographic signaling as not permitted is the holographic one.
