B)Phosphorous only
C)Calcium and Phosphorous
D)Iron

Answer 1

Hint: Proper nutrition is important for growing individuals. Nutrition comes from vitamins and minerals, which comes from the food we consume. Different parts of our body need specific amounts of vitamins for proper growth and achieving overall health.

Complete answer:
Our body needs both vitamins and minerals for proper growth and functioning. The minerals which are required essentially by the body are termed as essential minerals. Based on the amount they are needed, essential minerals are divided into macrominerals and trace minerals (microminerals).

Sodium	Proper fluid balance, nerve transmission, and muscle contraction
Chloride	Proper fluid balance, stomach acid
Potassium	Proper fluid balance, nerve transmission, and muscle contraction
Calcium	Healthy bones and teeth, muscles relaxation and contraction, nerve functioning, blood clotting, blood pressure regulation
Phosphorus	Healthy bones and teeth, maintains acid-base balance
Magnesium	Making protein, muscle contraction, nerve transmission

Trace minerals (microminerals):

Iron	Part of a molecule (hemoglobin) found in red blood cells that carries oxygen in the body, needed for energy metabolism
Zinc	Needed for making protein and genetic material, taste perception, wound healing, normal fetal development, production of sperm, normal growth and sexual maturation, immune system health
Iodine	Helps to regulate growth, development, and metabolism
Selenium	Antioxidant
Copper	Needed for iron metabolism
Manganese	Part of many enzymes
Fluoride	Involved in formation of bones and teeth, prevent tooth decay
Chromium	Regulates blood sugar (glucose) levels
Molybdenum	Part of some enzymes

Hence, the correct answer is option (C)

Note: Some other trace nutrients which are essential but required in small amounts include nickel, silicon, vanadium, and cobalt. Vitamin D regulates the body's balance of calcium and phosphorus and promotes absorption. It also helps in reducing the inflammation of gums. Apart from all the minerals, a healthy diet is essential for healthy teeth.
