The correct option is (d) Iron.
Further Explanation:
Iron is the significant mineral for the proper functioning of haemoglobin. In the “red blood cells”, iron combines with “protein” which is referred to as haemoglobin.
The iron plays an important role in the “red blood cells” where iron helps in carrying oxygen to the body’s tissues and cells. If there is a deficiency of iron in the human body then it causes memory, behaviour and concentration problem. This is seen particularly in the children. The children with an iron deficiency tend to have a poor attention span and bad in academics than their classmates.
Iron deficiency can also cause “spoon-shaped fingernails” (called koilonychia) and also soreness at the corners of tongue and mouth. The iron deficiency may also lead to the development of “restless legs syndrome”. It also leads to iron deficiency anaemia in people. It occurs when an individual body’s iron stores function so low that it doesn’t make a proper amount of haemoglobin.
