Answer: D. [tex]V_2O_5[/tex]

Explanation: Ionic compound is formed by transfer of electrons from metal to non metal.

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here vanadium is having an oxidation state of +5 and oxide is a ion with oxidation state of -2. Thus on exchange of their oxidation states, they combine to form neutral [tex]V_2O_5[/tex].
