Answer 1

Answer: Water

Reason :

• It is necessary for many chemical reactions in the body as well as for maintaining the correct osmotic pressure in the cell.
• Water is also a natural solvent and helps to dissolve many nutrients in it as well and carry them from one cell to another through the blood as it is easily diffusible.
