The more we consume renewable sources lesser they become available in our lifetime. 

Soil Erosion is a major cause of land degradation in our country, where the fields upper layer of soil is displaced.

Petroleum, Coal and natural gas are fossil fuels.

Trees are renewable resource of fuel as they can be planted new and can be recreated. So renewable natural resources are Trees. Hence, option A is correct.

Advantage of use of natural gas as fuel is that natural gas releases fewer pollutants which can decrease the pollution.

Coal reserves may last for a few hundred years but at the present rate of consumption, the present coal reserves might run out of coal sooner than expected.

Coal and petroleum are formed from the dead remains of organisms and are known as fossil fuels.

Excessive burning of fossil fuels is a major cause of "GLOBAL WARMING".

Explanation :
Carbon dioxide (CO2), which, while not  the most potent greenhouse gas, 

is nevertheless the main driver of the greenhouse effect. When fossil fuels - coal, oil and natural gas - are burnt they release CO2 into the atmosphere. Because of this, the layer of greenhouse gas is getting thicker, which is, in turn, making the Earth warmer. Thus the ongoing unlimited burning of fossil fuels is the cause of climate change and global warming.

Kerosene on burning provides a large amount of energy and hence used as fuel in jet crafts.

Depletion of natural resources like water, fuel-air and soil produces competition among living organisms for the remaining portions and diminishes the quality of available resources. Some of the human activities reduce the quality of drinking water. Overuse of fossil fuels reduces their availability and also introduces harmful toxins into the water and the atmosphere. Deforestation and agricultural activities exacerbate erosion and cause soil contamination, which impairs the survival capacity of plants, and makes surrounding areas prone to flooding and environmental disasters.
