Which of the following pair of mineral - need is correct?

I. Iron - formation of hemoglobin

II. Sodium - proper functioning of thyroid

Only I

The correct answer is option 4. Only I.

The correct pair of mineral and its function is: I. Iron - formation of hemoglobin

I. Iron - formation of hemoglobin:

Iron is an essential mineral that plays a crucial role in the formation of hemoglobin. Hemoglobin is a protein in red blood cells that binds with oxygen in the lungs and carries it to tissues throughout the body. Iron is a key component of the heme group in hemoglobin, which is responsible for binding and transporting oxygen.

II. Sodium - proper functioning of the thyroid:

This statement is not correct. Sodium is not directly involved in the proper functioning of the thyroid. The thyroid gland primarily requires iodine for the synthesis of thyroid hormones, such as thyroxine (T4) and triiodothyronine (T3).

So, the correct pair is I. Iron - formation of hemoglobin. Therefore, the correct answer is 4. Only I.
