Solution

The correct option is A True
Iron (II,III) oxide is the chemical compound with formula $F e_{3} O_{4}$ . It occurs in nature as the mineral magnetite. It is one of a number of iron oxides, the others being iron(II) oxide ( $F e O$ ), which is rare, and iron(III) oxide ( $F e_{2} O_{3}$ ) also known as hematite. $F e_{3} O_{4}$ contains both $F e^{2 +}$ and $F e^{3 +}$ ions and is sometimes formulated as FeO ∙ Fe₂O₃.
