What are the correct answers to these chemistry questions regarding aluminium oxide and group IIIA elements?

Here are the solutions to the chemistry questions:

Q.1. Aluminium oxide ($\text{Al}_2\text{O}_3$) reacts with both acids and bases, which is the definition of an amphoteric substance.

• The correct option is (C) amphoteric.

Q.2. Group IIIA (Group 13) elements have 3 valence electrons, typically with an $\text{ns}^2 \text{np}^1$ configuration. Option (A) shows $3\text{s}^2 3\text{p}^1$, which corresponds to Aluminium, a Group IIIA element.

• The correct option is **(A) $1s^2 2s^2 2
