Answers #1 & #2 is correct but i can add something for the the benefit of some.
In ONAN the oil in the TX former circulates on its own due to hot oil goes up & cooler oil goes down.The TX former is cooled by just the air around it.
In ONAF the oil circulates as above but a fan is used to cool it.
In OFAF the oil is pumped with a pump for circulation and the air is cooled by a fan.
In DYN the primary winding of the tx former is wound in delta and the secondary is wound in star with tapping for neutral connection.
