B Correct answer
Explanation

Optic fiber cables transmit data using light pulses, enabling extremely high speeds (gigabits to terabits per second). Coaxial cable (A) and twisted pair/UTP (C, D) use electrical signals and have much lower bandwidth limits due to electromagnetic interference and signal degradation. Fiber optics are the fastest transmission medium for long-distance data communication.
