    D) At place Y, renewable energy sources are fastly replacing the use of conventional energy sources.

    Correct Answer: B

    The pH level of rainwater (precipitation) at place Vis around 4 that means rainwater is acidic at place Y. As an impact of acid rain at place Y we can find yellowing of marble statues and plants with burnt leaves. It also indicates that use of fossil fuels (conventional energy sources) is much higher at place X than place Y.
