Option 1: Only I
Option 2: Both I and II
Option 3: Neither I nor II
Option 4: Only II
Correct Answer: Only II
Solution : The correct option is Only II
Micronutrients are nutrients that are required by the body in smaller amounts compared to macronutrients. Calcium is indeed a micronutrient. Other examples of micronutrients include vitamins (such as vitamin C, vitamin A, etc.) and minerals (such as iron, zinc, etc.).
Macronutrients are nutrients that are required by the body in relatively large amounts. Iron, however, is a micronutrient, not a macronutrient. Iron is essential for various physiological processes in the body, including the formation of haemoglobin.
