Answer:
Option C, It can regulate temperature
Explanation:
Carbon atom is able to form bonds with other carbon atoms or atoms of hydrogen , oxygen , nitrogen , phosphorus etc. A carbon forms a diamond/graphite when it joins cohesively while they form molecules like hydrocarbons, CO2 etc, when it joins adhesively with other than carbon atoms. Thus Option A is incorrect
Since carbon combines with other chemical atoms to form polymers, lipids , proteins etc, as they are adhesive to other than carbon atoms. Option B is also incorrect.
Option C, is a physical phenomena in which carbon compounds do not allow heat to escape from earth and in this way it regulate the temperature of earth. This is not an internal property of carbon and hence option C is correct.
Option D is incorrect as carbon can be easily decomposed along with production of energy by decomposers or by burning the fuels containing carbon.
