(i) It is an acidic oxide and anhydride of ${HNO}_{2}$
$N_{2} O_{3} + H_{2} O \to 2 H N O_{2}$
(ii) With alkali it forms nitrites
$N_{2} O_{3} + 2 N a O H \to 2 N a N O_{2} + H_{2} O$
(iii) It can also be prepared by the action of 50% $H N O_{3}$ on arsenious oxide and then cooling to 250 K
All are correct here.
