Answer:

D. single-mode ļ¬ber-optic cable

Explanation:

Only the single-mode ļ¬ber-optic cable is able to travel the distance of 60 kilometers. although it is known optic cables in general are the most advanced in data transmission, the multimode cable is not able to transfer a signal to that distance. Shielded twisted pair cable and a coaxial cable are older cables that are not that advanced distance-wise.
