Other than B (I don't count that one), it's cause they actually look like men. Plus A at least - which is a bit too tall admittedly - has elegant features, and would probably match closely to an official concept. The thing about being taller in this game, is they can be bigger (broader; musculature) without being overly jacked. Fitting for a male. Midlanders would look like little boys in comparison, and actually a lot of them do already..
