Which of the following is correctly matched?
A
Basic oxides $\Rightarrow In_2O_3, K_2O, SnO_2$
B
Neutral oxides $\Rightarrow CO, NO_2, N_2O$
C
Acidic oxides $\Rightarrow Mn_2O_7, SO_2, TeO_3$
D
Amphoteric oxides $\Rightarrow BeO, Ga_2O_3, GeO$
Detailed Solution
$Mn_2O_7$, $SO_2$, and $TeO_3$ are all acidic oxides, making option (3) the correctly matched pair. (Option 1 wrongly classes $SnO_2$, which is amphoteric, as basic; option 2 wrongly classes $NO_2$, which is acidic, as neutral; option 4 wrongly classes $GeO$ among amphoteric oxides.)
