High tension transmission is characterized by low current and high voltage. Therefore, the correct answer is B.
High voltage is used in power transmission to minimize energy loss due to resistance in the wires. According to the formula P=VI (power = voltage x current), at a constant power, higher voltage results in lower current. Lower current reduces heat loss (I²R loss) in the conductors. High-tension cables typically carry over 1000 volts between conductors.
