What was an advantage of alternating current (AC) electricity?

It was powerful enough to run motors.

It allowed electricity to be carried longer distances safely.

It enabled electricity to work in both small and large appliances.

It was inexpensive enough to use in homes.

Alternating current (AC) is easy to generate and use, with numerous advantages over direct current (DC). AC can be transmitted over long distances using step up transformers, is easier and cheaper to generate than DC. The AC generators have higher efficiency than DC and the loss of energy during transmission is negligible for AC. From the given statements the following is true:

It allowed electricity to be carried longer distances safely.
