    A I only Correct Answer Incorrect Answer
    B I and II Correct Answer Incorrect Answer
    C II and III Correct Answer Incorrect Answer
    D I, II, and III Correct Answer Incorrect Answer

    Solution

    Statements I and II are correct. Rachel Carson's Silent Spring played a pivotal role in raising awareness about environmental degradation, particularly concerning pesticide use, helping to spark the modern environmental movement. The first Earth Day, indeed held in 1970, significantly increased environmental awareness. However, statement III is incorrect as the Montreal Protocol was actually aimed at addressing the depletion of the ozone layer, not global warming.
