Solution

The correct option is A high potential and low current
Power wasted as heat is $V^{2} / R a n d I^{2} R$ . In long distance transmission of electricity ,long wires are used which have very high resistance , $R \propto l$ , so direct multiplication of R into a high number will increase Power wasted ,so current should be low ,voltage can be high because resistance is denominator so it will reduce the power wasted as heat.
So less power is wasted therefore it is more economical way.
