In Ohm's law, if current doubles while resistance stays the same, voltage will

Explanation:
Voltage equals current times resistance, so with resistance fixed, voltage scales directly with current. If the current doubles, voltage doubles as well. For example, if R is 5 ohms and I goes from 2 A to 4 A, V goes from 10 V to 20 V. The other possibilities don’t fit because quadrupling current would be needed to quadruple voltage, keeping voltage the same would require current to stay the same (or resistance to be zero), and halving current would halve the voltage. Therefore, the voltage will double.
