Answer:
Option B
Explanation:
Zn(zinc) element of forms amphoteric oxide .i,e, ZnO. This oxide reacts with both acids and bases, exhibiting a dual behaviour. They show characteristics of both acidic as well as basic oxides
Following reactions are given by ZnO
$ZnO+2HCl\rightarrow ZnCl_{2}+H_{2}O$
$ZnO+2NaOH\rightarrow Na_{2}ZnO_{2}+H_{2}O$
Note: Among oxides, CO is neutral, CaO is basic and SO2 is acidic in nature
