Answer: The correct option is 3.

Explanation: We are given a compound which is made up of iron and oxygen only. The ratio of the two are given as:

\frac{\text{iron ions}}{\text{oxide ions}}=\frac{2}{3}

This means that, number of iron ions are 2

Number of oxide ions are 3

From the above information, the formula becomes : Fe_2O_3

The valency of iron = 3

Valency of oxide = 2

This compound is named as iron (III) oxide.

Hence, the correct option is 3
