Voltage is the force the pushes the electrons down a wire...regardless of how many electrons are involved.

B is correct.

The higher the voltage AND the larger the current (numbers of electrons) the greater the work that can be done, called watts many times... current is also called amperage.

Volts x amps = watts is the same as voltage x current = power.

So that B is correct, A is incorrect.
