How Is Three Phase Electricity Created at a Power Station

How is three phase electricity created at a power station?

A) Each alternator has three stator coils so one revolution of the rotor generates three separate sine wave outputs
B) Three single phase alternators have interconnected output power circuits
C) Single phase generators with rectifiers creating three phases
D) Multiple transformers create three phases
E) Three single phase alternators each power one line voltage; each building takes all three lines to have three phase power
