A) Assertion is correct as $C_{4}$ plants are photosynthetically more efficient than $C_{3}$ plants. Reason is correct and is the correct explanation of Assertion as $C_{4}$ plants are more efficient as they recycle carbon dioxide and are more efficient in picking of carbon dioxide, which also conserves energy.
B) Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
C) Reason is correct.
D) Both Assertion and Reason are correct.
So the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
