The correct answer is D. Super phosphate.
Ammonium sulphate, urea, and ammonium nitrate are all nitrogenous fertilizers. Super phosphate is a phosphate fertilizer.
Ammonium sulphate is a white, crystalline solid that is soluble in water. It is a common fertilizer that is used to provide nitrogen to plants. Urea is a white, crystalline solid that is also soluble in water. It is a very concentrated form of nitrogen and is often used as a foliar fertilizer. Ammonium nitrate is a white, crystalline solid that is also soluble in water. It is a strong oxidizer and can be explosive if mixed with other materials.
Super phosphate is a mixture of calcium sulfate and phosphoric acid. It is a common fertilizer that is used to provide phosphorus to plants.
