Final answer:
The assertion is false(B) as historical and empirical evidence shows that pollution levels do have an impact on moth color distribution due to industrial melanism. With less pollution, we would expect lighter moth forms to be favored again.
Step-by-step explanation:
The statement suggesting that there is no correlation between the prevalence of dark forms of moths and the pollution levels in an area is false(B). The well-documented phenomenon known as industrial melanism shows that during the Industrial Revolution, polluted areas favored dark-colored moths (melanic forms) because they were better camouflaged against the soot-covered trees, leading to increased survival against predation. Conversely, as industries have become cleaner and pollution levels have dropped, resulting in less soot on trees, we'd expect the lighter-colored moths to be favored once more. This shift towards cleaner factories would likely lead to a change in the moth population, causing an increase in the prevalence of light forms.
