Using the graphs below , which group of moths is better adapted to survive the hunting cycle

The correct answer is C.

As we can see in the graph above, there is a great difference in survival of moths of different colors in different habitats ( light and dark trees).
Light moths are more successful on light trees than the dark moths, the dark moths have higher survival rates on the dark trees.

But, the difference in survival rates is greater on dark trees than in the light trees.
As we can see, the dark moths have an almost 100 % survival rate on the dark trees, compared to around 70% for light moths on light trees.
Therefore, we can conclude that the dark moths on the dark trees are the most successful.

Probably a behavioral adaptation
