The correct Answer is:
To answer the question regarding the discovery of a new nutrient, we can follow these steps: ### Step 1: Understand the Types of Nutrients - Nutrients are classified into two main categories based on their required amounts by plants: macronutrients and micronutrients. - Macronutrients are required in larger quantities (more than 10 millimoles per kg), while micronutrients are needed in smaller amounts (less than 10 millimoles per kg). ### Step 2: Analyze the Options - The options provided are: 1. Micronutrient 2. Macronutrient 3. Rare gas 4. ARB (which is not a recognized category of nutrients) ### Step 3: Eliminate Incorrect Options - Rare gases are not considered nutrients for plants, so this option can be eliminated. - ARB is not a recognized term in the context of plant nutrition, so this option can also be eliminated. ### Step 4: Determine the Correct Category - Since the question asks about a new nutrient, it could either be a macronutrient or a micronutrient depending on the quantity required by the plant. - If the new nutrient is required in large amounts (more than 10 millimoles per kg), it would be classified as a macronutrient. - If it is required in smaller amounts (less than 10 millimoles per kg), it would be classified as a micronutrient. ### Step 5: Conclusion - Therefore, the correct answer to the question is that if a new nutrient is discovered, it would be either a macronutrient or a micronutrient (options 1 or 2). ### Final Answer - The correct answer is: **Option 1 (Micronutrient) or Option 2 (Macronutrient)**. ---
