Solution

The correct option is C Black colour saved the moths from predation
Black coloured moths were saved from predation as they were able to camouflage very easily in the soot covered polluted environment of the Industrial Revolution period. On the other hand, white moths stood out even more in the changing background and were subject to increased predation.
