Assertion : The atmospheric concentration of \[C{{O}_{2}}\]at which photosynthesis just compensates for respiration is referred to as \[C{{O}_{2}}\] compensation point. Reason : The \[C{{O}_{2}}\]compensation point is reached when the amount of \[C{{O}_{2}}\] uptake is less than that generated through respiration because the level of \[C{{O}_{2}}\] in the atmosphere is more than that required for achieving \[C{{O}_{2}}\] compensation point.

• A. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
• B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion 
• C. If the assertion is true but the reason is false
• D. If both the assertion and reason are false
• E. If the assertion is false but reason is true
