To solve this problem, we need to identify which minerals are required in large amounts for plant growth. These are known as macronutrients.$\newline$Let's analyze each option:$\newline \bullet$Option 1: Phosphorus, potassium, sulphur, calcium$\newline$ - Phosphorus (P) is a macronutrient essential for energy transfer and photosynthesis.$\newline$ - Potassium (K) is crucial for enzyme activation and osmoregulation.$\newline$ - Sulphur (S) is important for protein synthesis and chlorophyll formation.$\newline$ - Calcium (Ca) is necessary for cell wall structure and stability.$\newline$ - All these elements are macronutrients required in large amounts.$\newline \bullet$Option 2: Calcium, magnesium, manganese, copper$\newline$ - Calcium (Ca) and magnesium (Mg) are macronutrients.$\newline$ - Manganese (Mn) and copper (Cu) are micronutrients, needed in smaller amounts.$\newline \bullet$Option 3: Potassium, phosphorus, selenium, boron$\newline$ - Potassium (K) and phosphorus (P) are macronutrients.$\newline$ - Selenium (Se) and boron (B) are micronutrients.$\newline \bullet$Option 4: Magnesium, sulphur, iron, zinc$\newline$ - Magnesium (Mg) and sulphur (S) are macronutrients.$\newline$ - Iron (Fe) and zinc (Zn) are micronutrients.$\newline$Based on the analysis, Option 1 contains only macronutrients, which are required in large amounts for plant growth.$\newline$Therefore, the correct option is Option 1.
