Group 13 elements react with oxygen to form oxides with the general formula M2O3, where M is the group 13 element. The oxides formed are amphoteric in nature, which means they can act as both acids and bases. The stability of the oxide increases down the group due to an increase in ionic character. However, group 13 elements do not react vigorously with oxygen at room temperature.

Option 1) is incorrect because group 13 elements do form oxides with the general formula M2O3.

Option 2) is incorrect because the oxides formed are amphoteric in nature.

Option 3) is incorrect because the stability of the oxide does increase down the group.
