W) The shape is distorted when capacitors and inductors are present in a circuit

X) The shape is preserved when capacitors and inductors are present in a circuit

Y) The need for capacitors and inductors is eliminated, making the power factor very close to 1

Z) The shape guarantees that no power outages will occur
