Explanation:

To determine what caused the trees to change color and look darker, we analyze the options:

• Forest fires typically burn or char trees, but the question implies a more gradual, pollution - related darkening.
• A disease spread by a tree fungus would likely cause symptoms like wilting, abnormal growth, or discoloration related to the disease, not a general darkening from soot.
• Soot from an increasing number of factories is a form of air pollution. Soot can settle on trees, covering their surfaces and making them appear darker. This is consistent with industrial pollution impacts on the environment.

Answer:

C. Soot from an increasing number of factories
