            Answer is Wrong!
            Answer is Right!
        The correct answer is D. All of the above.
High-voltage transmission lines are essential for transporting electricity over long distances, reducing power losses, and ensuring grid stability.
- High-voltage transmission lines can carry electricity over long distances with minimal loss of power. This is because the higher the voltage, the lower the current, and the lower the power loss due to resistance.
- High-voltage transmission lines can also help to ensure grid stability. This is because they can quickly and easily transfer power from one part of the grid to another, which helps to balance the load and prevent blackouts.
In conclusion, high-voltage transmission lines are essential for transporting electricity over long distances, reducing power losses, and ensuring grid stability.
