Which of these is a characteristic feature of adult African buffalo horns?

aren't they all characteristics?

Ali *Regulus* Mirza, Then they should’ve said the “most distinguishing”.

Player #12969645, I'm sure they meant 'the most distinguishing characteristic feature'. Animals of many other species might have horns with roughly the same colour and/or size, but it's the shape of an adult male cape buffalo's horns that's most readily recognisable.
