Solution

The correct option is A Iron
Minerals are the nutrients required in small amounts for the body to perform various functions.
  • Blood contains a protein called hemoglobin. Iron is an important component of hemoglobin present in the red blood cells. This protein gives blood the ability to carry oxygen.
  • Bones and teeth have higher concentration of minerals such as calcium and phosphorus which strengthens bones and teeth.
  • Iodine controls the growth and also helps in speeding up the chemical reactions in the body.
