Correct option: C.
$Cr_2O_3$
c
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 $Cr _2 O _3$ can show the property of acidic as well as basic oxide both.
