(C) Amphoteric oxides are those that react with both acids and bases.$Cr_2O_3$ is a well-known amphoteric oxide.$V_2O_5$ also exhibits amphoteric character,although it is predominantly acidic,it reacts with strong bases to form vanadates and with strong acids to form oxovanadium ions.$Mn_2O_7$ and $CrO_3$ are acidic oxides.$CrO$ is a basic oxide.$V_2O_4$ is a basic oxide.Therefore,the correct pair is $V_2O_5$ and $Cr_2O_3$.

Which of the following are amphoteric oxides?
$Mn_2O_7, CrO_3, Cr_2O_3, CrO, V_2O_5, V_2O_4$
