Hint:

Coal-fired power plants are significant sources of mercury emissions, which can have harmful effects on human health and the environment.

Answer 1

The Correct Option is C

Coal-fired power plants produce a variety of emissions, with mercury being one of the key pollutants released. Mercury is a toxic substance that can accumulate in the environment and the food chain, posing significant health risks.

Step 1: Identify the emission.
Coal combustion leads to the emission of several pollutants, including mercury (Hg), which is released as a vapor during the burning of coal. Other substances like sulfur dioxide, carbon dioxide, and nitrogen oxides are also produced.

Step 2: Conclusion.
Therefore, coal-fired power plants emit mercury (Hg) as one of their major pollutants.
