Directions: Select the correct graph. A moth population living in a deciduous forest relies on camouflage to protect itself from predators. These moths typically vary in color and are thus able to camouflage among both the light- and dark-colored trees of the forest. However, as soot emitted from nearby factories darkens the forest's trees, the moth population begins to evolve. Which of the following distribution graphs best represents the evolution of this moth population?
A
B
C
