Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understand amphoteric oxides.
Amphoteric oxides are those oxides which react with both acids and bases.
They show both acidic and basic nature.
Step 2: Analyze each oxide.
\[ ZnO \] is amphoteric because it reacts with both acids and alkalis.
\[ Tl_2O_3 \] is mainly basic in nature.
\[ In_2O_3 \] is generally basic in character.
\[ B_2O_3 \] is an acidic oxide.
\[ PbO \] is amphoteric and reacts with both acids and bases.
\[ SnO_2 \] is also amphoteric in nature.
Step 3: Identify the correct set.
Thus, the amphoteric oxides are \[ ZnO,\ PbO,\ SnO_2 \]
Step 4: Final conclusion.
Hence, the correct answer is \[ \boxed{ZnO,\ PbO,\ SnO_2} \]
