The correct option for chemically balanced equation is - d. 3Fe + 4[tex] H_{2}[/tex]O > [tex] Fe_{3}[/tex][tex] O_{4}[/tex] + [tex] H_{2}[/tex].

The mentioned chemically balanced reaction states reaction between iron and water to produce iron oxide and hydrogen. Fe represents iron, [tex] H_{2}[/tex]O represents water, [tex] Fe_{3}[/tex][tex] O_{4}[/tex] represents iron (II, III) oxide and [tex] H_{2}[/tex] represents hydrogen.

Iron oxides are commonly found in human body and environment. It is present in body as haemoglobin and in nature as ores. The applications are as catalyst, paints, concretes, thermites etc. Iron oxides possess multiple properties including large surface area, magnetic properties and low toxicity. The low toxicity makes it a suitable candidate for therapeutic purposes in human body by participating in drug delivery, magnetic coatings, biosensors, and other purposes like wastewater purification, magnetic data storage etc.
