The transformer's job is to keep the voltage stable, not to mess with the power factor or impedance. Option C is the way to go.

Haha, a transformer increasing harmonics? That's like a mechanic making your car run worse! Definitely not the right answer there.

I'm not sure about the others, but I know that a transformer is not used to increase harmonics, so I can rule out option B.

I'm not sure about the other options, but I think C makes the most sense. It's important for the UPS to provide consistent power to the connected devices.

Option C seems to be the correct answer. A transformer in a line interactive UPS is used to regulate the output voltage as the input voltage varies.

I agree with Simona. The transformer helps maintain a stable output voltage despite fluctuations in the input voltage.
