According to Ohm's Law, the current (in mA) is directly proportional to the number of electrons flowing. Therefore, if the mA doubles, the electron flow will also double. Thus, the correct answer is B - the number of electrons flowing from cathode to anode increases twofold.

As the MA Doubles, the Number of Electrons Flowing from Cathode
