The resources which are available in nature in an unlimited amount are known as inexhaustible resources. These resources can be replenished again and again for use. The resources which can be renewed and are safe to use are known as non-conventional sources of energy. Solar radiations, wind power and sea tides are used for the generation of the electricity. These are inexhaustive and non-conventional resources. 

The resources which cannot be replenished again after consumption of resources are known as non-renewable resources. Coal is obtained from the Earth's crust due to the decomposition of the dead matter for long period of time. It is commonly used as the source of energy. There are limited deposits of coal present and they take a long time to be formed. so, they are known as non-renewable form of energy. 

The resources which can be replenished again after their consumption are referred as the renewable sources of energy. The forest biomass is considered as a great source of energy in the form of wood, charcoal, etc. The forests serve as the renewable energy source. The forests can be replenished by the method of afforestation. 

The minerals are obtained from the ores through mining. There are limited resources of the minerals present in the Earth's crust. Tin is used for various purposes from the ancient age. Tin was used for the making of coin, utensils, alloy making, etc. Tin is now commonly used for the preparation of the jars. The exploitation of the metal has resulted in fewer resources left and so, the metal resource will be exhausted first.

Conventional resources are those that have been used for a long time and are generally finite. These are typically non-renewable resources like coal, petroleum, and natural gas.

Renewable resources are those that can be replenished naturally over time. Water is part of the hydrological cycle and is considered a renewable resource, whereas coal, fuels, and minerals are finite.

The resources which are available in nature in an unlimited amount are known as inexhaustible resources. These resources can be replenished again and again for use. The solar energy is obtained from the radiations of the sun is an example of an inexhaustible resource. The energy is a safe energy source and does not cause any type of pollution.

The resources which can be replenished again after their consumption are referred as the renewable sources of energy. The forests can be replenished through afforestation. The programs like hugging the tree, tree plantation program, etc have been undertaken in order to increase the forests resources.

Biomass is organic material formed by the decomposition of dead plants and animals. The living forms such as plants and animals can be replenished by reproduction. Hence, biomass is a renewable and sustainable source of energy. It is used to generate electricity or other forms of energy. Thus the correct answer is option D.

Minerals are finite resources that take millions of years to form. Because they are limited and have been traditionally used for industrial development, they are classified as conventional resources.
