Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Land plants get gaseous CO $_{2}$ from the atmosphere which is utilized in photosynthesis. The atmospheric CO $_{2}$ enters into the leaf through stomata. But submerged plants do not have stomata, So no CO $_{2}$ entry occurs through stomata. So, they get carbon dioxide in the form of carbonates and bicarbonates via absorption from the body surface.
Hence, the correct answer is 'Both Assertion and Reason are correct and the reason is the correct explanation for Assertion'.
