Final answer:
The statement is false; high voltage and low current are used for efficient power transmission to minimize losses due to the resistance of transmission lines. Hence, option (B) is correct.
Step-by-step explanation:
The statement 'A high current should be used when transmitting electricity so that less power will be lost' is false. When transmitting electrical power over long distances, it is more efficient to use high voltage and low current.
This is because power loss due to resistance in the wires (Joule losses) is proportional to the square of the current (Plost = I2R), where I is the current and R is the resistance. By increasing the voltage and lowering the current, power loss can be significantly reduced. Transforming the high voltage back to a safer, lower voltage for residential use is achieved with transformers before it enters homes.
