A Correct answer
Explanation

The Japanese Shinkansen (bullet train) system uses 25,000 volt AC overhead power supply for most of its lines. This voltage standard was chosen to efficiently power the high-speed trains while minimizing power losses over long distances. The 25 kV AC system is common internationally for high-speed rail. Lower voltages would have higher power loss, while significantly higher voltages would require more expensive infrastructure. This voltage has been used since the first Shinkansen line opened in 1964.
