The minimum power required to start the UH-72A is ______ Volts.

Explanation:
The starting process needs enough voltage to feed the starter motor under load. The UH-72A uses a 28-volt DC system, and when you crank, the battery voltage can sag. The minimum voltage that still allows reliable cranking is 23.5 volts, which is why 23.5 volts is the correct choice. Values higher than that (like 25 or 28.5 volts) will work too, but they aren’t the minimum threshold, while a voltage around 20 volts is typically too low to start.
