Final answer:
AC is the preferred form of current for transmitting energy over large distances because it enables higher currents and allows for voltage transformation through the use of transformers.
Step-by-step explanation:
The correct answer is AC, because it allows higher currents to be transmitted over large distances. Although AC and DC currents both have their advantages and disadvantages, AC is typically preferred for long-distance transmission due to its ability to easily transform voltage levels through the use of transformers. These transformers allow for efficient stepping up and stepping down of voltage, which makes it easier to transmit energy over long distances.
