Segment B - Citroën C3, DS3, Peugeot 208, Hyundai i20 (before it was Getz), Ford Fiesta, Fiat Punto, VW Polo, Škoda Fabia, Kia Rio etc.
Segment C - Citroën C4, Peugeot 308, Hyundai i30, Ford Focus, Fiat Bravo, VW Golf, Kia Cee'd etc.
It has not much to do with copying rather than using a brain. Segment B cars are ideal for making cars under current rules. C-ones are too big and heavy, A-ones are too small. Also it's logical to use same class car as Your opponent for marketing purposes - they compete with each other like on the market.
