The correct answer is C. Russia and China have the largest electrified railway network in the world.
Russia has the largest electrified railway network in the world, with a total of 47,000 kilometers of electrified track. China is the second largest, with 38,000 kilometers of electrified track. The United States has the third largest electrified railway network, with 22,000 kilometers of electrified track. India has the fourth largest electrified railway network, with 16,000 kilometers of electrified track.
The electrification of railways has a number of benefits, including:
- Increased efficiency: Electric locomotives are more efficient than diesel locomotives, which means that they can haul more freight or passengers with less fuel.
- Reduced emissions: Electric locomotives produce fewer emissions than diesel locomotives, which helps to improve air quality.
- Increased reliability: Electric locomotives are less likely to break down than diesel locomotives, which means that trains are more likely to run on time.
- Reduced noise: Electric locomotives are quieter than diesel locomotives, which can reduce noise pollution in urban areas.
The electrification of railways is a major investment, but it can provide a number of benefits for both countries and the environment.
