Explanation
Option A is correct because smart city network architecture is built on a layered model, and the optical transmission layer serves as the physical foundation - the "most basic" tier upon which all higher-level data communication depends. Without this physical infrastructure (fiber optic cables and related hardware), no digital information could travel between sensors, platforms, and applications across the city network. Option B is incorrect because dismissing optical transmission as non-foundational misunderstands the OSI-style hierarchy: higher layers like network protocols, platforms, and applications all rely on the physical transmission medium being in place first.
Memory tip: Think of optical transmission like the roads in a city - before you can have traffic rules (protocols), navigation apps (applications), or traffic management systems (platforms), the physical roads must exist. Optical fiber is the road of the smart city network.
