D) cyanobacteria, not plants. There is no doubt about it. Cyanobacteria made it possible for plants even to exist, and preceeded them by a long time.

I would say Plants.

It's true that some bacteria started to pour oxygen in the atmosphere, but the real 'revolution' started with plants.

For further details hear the Beatles' song 'Revolution' hehehe
