Answer:
A) Dark moths had a survival advantage in rural Birmingham.
Step-by-step explanation:
In the given graph, the data about dark moths are colored orange, and the data about light moths are colored green. We can clearly see this in the image I've attached below.
We can see that the percentage of recovered dark moths is greater in Dorset, while the percentage of recovered light moths is greater in Birmingham. This means that the dark moths had a survival advantage in Dorset, while the light moths had the advantage in Birmingham. This is why statement A is not supported by Kettlewell's data.
