I feel like the answer is true, but I need to double-check the definitions of the modes to be certain.

This seems straightforward to me. When the mains input exceeds the allowable range, the UPS will switch to static bypass mode. I'm feeling good about selecting the right answer here.

The key here is understanding what happens when the mains input goes out of the allowable range. Based on the information provided, I believe the correct answer is that the UPS will shift to static bypass mode.

Wait, I'm a bit confused. Does the question mean the UPS will be inverted from the main circuit, or that the mode will shift to static bypass mode? I need to re-read this carefully.

Okay, I think I understand the main idea here. When the mains input voltage and frequency exceed the allowable range, the UPS will shift to static bypass mode. I'm pretty confident this is the correct answer.

True - it makes sense for the UPS to switch to static bypass mode to protect the main circuit.

I'm going with B) False. Who wants their UPS to switch to battery power just because the mains voltage is a little high? That's just asking for trouble.

B) False, that doesn't sound right. The UPS should switch to bypass mode when the mains is within spec, not the other way around.
