The correct answer is option (d) atmosphere.
Fossil fuels are the hydrocarbons formed in the geological past, derived from the remains of dead plants and animals. They include the coal, fuel gas and the natural gas. The burning of fossil fuels is one of the greatest contributor of carbon dioxide being added to the atmosphere. This results in the pollution of air in the atmosphere resulting in the formation of smog. Carbon dioxide being a green house gas, affects the atmosphere and causes green house effect leading to global warming and climate changes.
The burning of fossil fuels affects the geosphere, biosphere and hydrosphere indirectly due to its primary direct effect on the atmosphere. Thus, atmosphere is directly affected by the burning of fossil fuels.

Answer:
They are building blocks for larger polysaccharide which are important in structural rigidity of cells.
Polysaccharides such as Starch and Cellulose which are instrumental in cell structure and rigidity are formed from chains of monosaccharides.
They are also useful in the provision of energy which is used in cell functions (metabolism).
Monosaccharides such as Glucose, Sucrose are useful in provision of energy for physical and metabolic activities of the body.
