How many power sources are available to an aircraft in-flight?

Explanation:
In-flight electrical power mainly comes from engine-driven generators, with the APU able to supply additional power if needed. The aircraft also carries a battery, used for engine start and as a short-term backup power source. So the common setup is two engine-driven generators, one battery, and an APU — four sources total. The other options add extra batteries or extra generators, which aren’t typical for standard in-flight power configurations.
