A.

Also increase by K times

B.

Increase by 1/K times

C.

Reduce to 1/K times

D.

Reduce to 1/K1 times

Answer ( Option D)

Reduce to 1/K1 times

Solution

Size of conductor (volume of conductor) is Aversely proportional to square of voltage.

Size of conductor


 If the transmission voltage increased K times the size of conductor reduce to  1/Ktimes.

Hence, the correct option is (D).
