Answer 1

The correct option is A N, P

ATP stands for adenosine triphosphate. Its main constituents are nitrogen and phosphorus. In plants, Nitrogen is mainly absorbed as nitrate, ammonium and nitrite form whereas phosphorus is absorbed as phosphate ions. N and P both are macronutrient and required by the plant in large amount.

So the correct answer is 'N, P'.
