Solution

The correct option is B It is amphoteric in nature
a) $Z n O$ is amphoteric in nature.
b) It is white when cold and yellow when hot.
c) Cobalt zincate $[C o (Z n O_{2})]$ is formed:
$2 Z n O + 2 C o (N O_{3})_{2} ⟶ 2 C o (Z n O_{2}) + 4 N O_{2} + O 2$
d) $Z n O$ is used as a catalyst along with $C r_{2} O_{3}$ in the manufracture of methyl alcohol from a mixture of carbon monoxide and hydrogen.
