Hint: Sodium chloride is normally known as table salt or common salt.
Sodium Chloride is an ionic compound with the chemical formula NaCl. It depicts an equal ratio of sodium ions and chloride ions in the ionic crystal.

Complete Step by Step Solution:
Sodium chloride is soluble in water and other polar solvents instantly. It is a stable solid. It disintegrates only at high temperatures by producing poisonous fumes of disodium oxide and hydrochloric acid. Sodium chloride is the reason for the salinity of seawater and the extracellular liquid of different multicellular organisms.

Sodium and potassium are present as electrolytes in the fluid inside and outside of our body cells. The equilibrium between these two particles contributes to the maintenance of energy in cells. NaI is primarily put into table salt for strengthening health. Iodine is an element that is required for the yield of thyroid hormones.

The thyroid hormone is the hormone that regulates the body's metabolism. Metabolism is the process by which our body changes food into energy. The two major hormones the thyroid sends out are thyroxine (\[{{\rm{T}}_{\rm{4}}}\] ) and triiodothyronine (\[{{\rm{T}}_{\rm{3}}}\]) which collectively comprise the thyroid hormone.

The body doesn't make iodine, so it must be an important portion of your diet. So, NaI is put into table salt for the healthy maintenance of the thyroid gland.
So, option C is correct.

Note: Sodium chloride is well-known as table salt and is widely utilised in the food enterprise for flavouring and preservation. It is utilised to yield different necessary chemicals like sodium hydroxide, baking soda, sodium carbonate, hydrochloric acid, and more. It is also used in the fabric industries, oil and petroleum refineries, paper and pulp industries, fire-extinguisher, building of roads, and rubber industries. It is utilised to yield sodium carbonate through the Solvay process.
