(a)

Interpretation Introduction

Interpretation:

From the given oxide pair ${\text{SO}}_{\text{2}}\text{or}{\text{SnO}}_{\text{2}}$, the one which is more basic has to be identified.

Concept introduction:

Basic oxide:

A basic oxide is an oxide which when combined with water gives off a base.

When a substance reacts chemically, both as a base or acid it termed as an amphoteric substance.
