Headphones are basically small speakers
and can be driven by any of those classes,
and there are a few more (G and H, for example).

It could be A, AB or D, depending on what you are connecting the headphones to.
An older HiFi amp will likely be Class AB.
A recent MP3 player will probably be Class D.
Bluetooth headphones are also likely class D as it's most efficient - but it's the designers choice, they coudl equally be Class AB.
Some dedicated headphone amps are Class A; but not all.
Class B is unlikely as they are prone to distortion - that's why AB is used, with some bias so both devices conduct to some extent at the crossover point.
