A. K.
B. Ca.
C. Mg.
D. Cu.

Answer 1

Hint: Nutrients are categorized into two categories, macronutrients and micronutrients. The elements that are present in small quantities in the body come under micronutrients whereas, the elements that are present in large amounts come under the category of macronutrients.

Complete answer:
Both types of nutrients whether micronutrients or macronutrients, both have the major role to play in the body.
Option A is incorrect as K stands for the element potassium. The element potassium K belongs to the important mineral present in the body as macronutrients. Some important functions are to help the body in nerve signals, to regulate fluid balance, and help in muscle contractions. It also protects from hearth strokes and kidney stones.
Option B is incorrect as Ca stands for the element calcium. The element Ca calcium belongs to the important mineral present in the body as macronutrients or large quantity in the bones of the body. Some important function of Ca is to help the body in bone formation, calcium pectate formation, nerve signals, etc.
Option C is also incorrect as Mg stands for the element magnesium. It acts as a cofactor to almost three hundred types of chemical reactions in the body. So it is present in a somewhat larger quantity as it helps hundreds of enzymes as cofactor. Therefore, it is the macronutrients.
Option D in correct as Cu stands for the copper element. It comes under the category of essential micronutrients present in the body. Iodine, cobalt, copper, molybdenum are also the microelements. It helps the body in the formation of RBCs red blood cells, healthy blood vessels, good immune systems, etc.

Hence, the correct answer is option (D).

Note: Nutrition in the body is an important process for the continuation of life. Generally there are total eight micronutrients, which are boron (B), chloride (Cl), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), nickel (Ni), and zinc (Zn).
