Answer: The answer is option D, leads to additional melting.
Step-by-step explanation:
As stated in the phrases that came before it, soot-covered snow has a darker surface, which melts more quickly since it heats up. In contrast, a whiter, soot-free surface would reflect heat. In contrast to ice and snow, which can reflect heat, uncovered land and water are likewise dark and incapable of doing so. Only option D accurately describes the self-reinforcing cycle that the phrases before it already suggest. Choices A, B, and C are inaccurate because the data they each present contradicts the statement made earlier that the soot's "outcome" is "a self-reinforcing cycle."
