Which of the following is a renewable source of energy?

Correct answer: (e) None of the above

Explanation

Renewable resources are those resources which are rapidly renewed or replenished. Some of them are inexhaustible and are not affected by human activities, such as solar energy, wind energy, etc. In contrast, non-renewable resources have limited reserves. After the reserves are exhausted, they take many years to be renewed or replenished. Coal, nuclear fuel, petroleum, and natural gas fall under this category.
