An example of cryptic coloration is the mottled colours on the moths that rest in lichens. Cryptic coloration, also known as camouflage, is a form of adaptation where an organism's appearance allows it to blend in with its surroundings and remain unnoticed by predators or prey. In this case, the mottled colours on the moths resemble the colours and patterns of the lichens that they rest on, making them difficult for predators to spot. This provides an advantage to the moth, as it is less likely to be eaten by predators. Therefore, the correct answer is option A: Mottled colours on the moths that rest in lichens.
