Solution

The correct option is D STATEMENT-1 is True, STATEMENT-2 is False

Be and Al form the amphoteric oxides, BeO and Al2O3 respectively. These oxides can behave both as base as well as acids.

Aluminium (Al) is a lightweight silvery-white metal and beryllium is also a steel-gray metal which is quite brittle at room temperature and resembles some of the properties of aluminium.

Hence, STATEMENT-1 is true and STATEMENT-2 is false.

Therefore, Option (C) is correct.
