Some dinosaurs had feathers although they could not fly but birds have feathers that help them to fly. In the context of evolution, this means that
a) reptiles have evolved from birds

b) there is no evolutionary connection between reptiles and birds

c) feathers are homologous structures in both the organisms

d) birds have evolved from reptiles
