Question : Which of the following is a non-renewable resource?
Option 1: Solar energy
Option 2: Wind energy
Option 3: Coal
Option 4: Geothermal energy
Correct Answer: Coal
Solution : The correct answer is (C) Coal
Coal is a fossil fuel formed from the remains of plants that lived and died millions of years ago. It is considered a non-renewable resource because it takes millions of years to form, and its extraction and combustion deplete its availability. Once coal reserves are depleted, they cannot be replenished within a human lifetime.
