Why can an Uninterruptible Power Supply not generally provide power for a long time?

Answer and explanation

Correct answer: Its battery stores limited energy and its main purpose is safe shutdown

The governing concept is limited stored energy. A UPS uses a rechargeable battery to bridge a short interruption, but battery capacity and the connected load determine runtime. More load consumes stored energy faster, so a typical UPS is intended to keep equipment running briefly or allow a safe shutdown, not to replace mains electricity for hours. Option B is correct; the other choices state false or irrelevant reasons.
