Detailed Solution

During the transmission  of electrical energy to a longer distance, the value of potential will be high and the value of current will be low.
For longer transmission power is kept at a constant rate. To make the power constant higher voltage and lower current is transmitted through the wire.To make it economical and lessen the power waste ,the resistance is chosen low and the voltage to be high. Likewise the power wastage can be reduced.
Hence, option(2) is correct.
