The correct answer is: A) Bullet trains.
Bullet trains are a type of high-speed rail that are designed to travel at speeds of up to 300 kilometers per hour. They are typically used to connect major cities and are often seen as a more efficient and environmentally friendly alternative to air travel.
The High-Speed Rail Corridor project is a proposed project that would connect major cities in Karnataka, India, with bullet trains. The project is still in the planning stages, but it has the potential to revolutionize transportation in the state.
Semi-high-speed trains are a type of train that travels at speeds of up to 200 kilometers per hour. They are typically used to connect smaller cities and towns and are often seen as a more affordable alternative to bullet trains.
Dedicated freight corridors are a type of railway line that is dedicated to the transportation of freight. They are typically used to transport goods over long distances and are often seen as a more efficient and cost-effective way to move freight than traditional railway lines.
