What would happen to the voltage if the current doubles and the resistance increases four times?

A The voltage will increase 8 times.
Explaination
Ohm's Law states that V=IR. If current doubles and the resistance increases four times then V = 2I * 4R = 8IR i.e. the voltage increases 8 times.
B The voltage will increase four times.
C The voltage will increase two times.
D The voltage will remain same.
