Solution

The correct option is D $V_{2} O_{5}, C r_{2} O_{3}$
In chemistry, an amphoteric species is a molecule or ion which can react as an acid as well as a base. This word is derived from the Greek word amphotericin which is meant for "both". Many metals like zinc, tin, lead, aluminium, beryllium, etc form amphoteric oxides or hydroxides.

Here both $V_{2} O_{5}$ and $C r_{2} O_{3}$ can show the property of acidic as well as basic oxide both.

Thus option A is correct.
