Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The production of carbon dioxide by combustion of fuel or oxidation of organic food in which carbon dioxide is the main gas which produces large amount but the level of carbon dioxide in the atmosphere is quite low. This because of the green plant which converts carbon dioxide to glucose by the process of photosynthesis and the coral reef are also using carbon dioxide for the making of the shell.
So, the correct option is 'Both assertion and reason are correct and reason is the correct explanation for assertion'.
