Correct answer: B. 1

Metallic oxides are basic in nature, Oxides of non-metals are mostly acidic in nature and some are neutral or amphoteric.

Among the given oxides ${Na}_{2}O$ is a metallic oxide, and it is basic in nature.

${Cl}_{2}{O}_{7}$ is a non-metal oxide and it is acidic in nature.

${N}_{2}O$ and $NO$ are non-metallic oxides but are neutral in nature.

${As}_{2}{O}_{3}$ is an Amphoteric oxide. It reacts with both acids and bases.

So, The number of amphoteric oxides is 1.

Given below are the oxides : Na _ 2 O, As _ 2 O _ 3 , N _ 2 O, NO...
