The answer is (B)
as we know the current i=v/r
by doubling the voltage, you can double the current through the wire.

For 50 amps, you’ll need a wire gauge of 6. Fifty amp breakers are most often used to power many different appliances. However, a kitchen oven can alone require 50 amps. Many electric dryers also require a 50 amp breaker.
You can calculate gauge with the wire size calculator https://electric-shocks.com/wire-size-calculator/May 1, 2021 at 1:16 am in reply to: what is the factor of b in shockley diode equation #5675
The assignment of B to a physical entity is done with the Boltzmann factor, where E is replaced by the voltage B: B = qV/kT, where k = 8.61758 x 105 eV/K. Then, kT/q is called the thermal voltage Vth and is 25.8 mV at 300K
