In which situation will the effect of natural selection be most clearly seen?

Answer and explanation

Correct answer: A colour that helps organisms hide from predators increases over generations

Natural selection acts on heritable variation when some individuals survive and reproduce more successfully than others. A colour that provides camouflage helps an organism escape predators, so its carriers may leave more offspring. If the colour is inherited, its frequency can increase over generations. Therefore option A directly shows selection, whereas identical organisms, no reproduction, or no environmental pressure provide no effective basis for selection.
