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
Correct Answer: E
Solution :
Plants absorb nitrogen in the form of \[NO_{3}^{-}\] (nitrate) or \[NH_{4}^{+}\] (ammonium ion). They can absorb \[NO_{2}^{-}\] (nitrite) as well but the same does not accumulate in the soil. Only a small quantity of nitrate or ammonium is available in the lithosphere. Therefore, nitrogen is the most critical element. Other critical elements are phosphorus and potassium.
