b and d are correct
The question is incredibly stupid because it asks for differences between fiber and copper cabling, but none of the answers make any comparison. Despite that, the two most correct answers are: ✅ B. The glass core component is encased in a cladding – a key structural feature of fiber optics, and ✅ D. Light is transmitted through the core of the fiber – which highlights how fiber transmits data (unlike copper, which uses electrical signals). The other options are incorrect because BNC and RJ-45 connectors are used with copper, not fiber, and data does not pass through the cladding.
