C)9.5 kΩ 
D)21.5 kΩ

Quizplus · Accepted Answer

The total resistance RT in a series circuit is the sum of all resistances: RT = R1 + R2 + R3 = 10 kΩ + 15 kΩ + 50 kΩ = 75 kΩ. However, since none of the options match this, it seems there might be a misunderstanding in the problem setup or options. If considering a parallel configuration, the calculation would be different, but based on the given options, 21.5 kΩ is the closest to a plausible scenario if there was an error in the problem statement.
