B Correct answer

Pollution is described as a threat to the environment. While pollution can cause diseases and might be considered a factor, "threats" best captures the danger and harm posed. The sentence structure "major threats to" is the standard collocation. "Symptoms" would describe effects of pollution, not pollution itself.
