Answer 1

Answer: (A), (B), (C)

The correct options are
A Coal is a non-renewable resource.
B Inefficient energy generation.
C Releases gases causing air pollution.

Coal is not a renewable source of energy. Power generation from coal is inefficient process. Only $30\%$ of the heat energy is converted to useful energy. Burning of coal releases sulphur dioxide and nitrogen oxides that cause air pollution, and they contribute to global warming. Hence, it is not an eco-friendly source of energy.
