Group 13 elements have a valence electron configuration of ns^{2}np^{1} . The other options are all true statements about the chemical properties of Group 13 elements. They form stable +3 oxidation states due to their tendency to lose their ns^{2}np^{1} valence electrons exhibit amphoteric behaviour because they can act as both acids and bases, and readily form compounds with halogens due to their electronegativity difference. Hence option 1 is the correct answer. 

Option(2) They form stable +3 oxidation states due to their tendency to lose their ns^{2}np^{1} valence electron. Hence option 2 is incorrect.

Option(3) They exhibit amphoteric behaviour because they can act as both acids and bases,  Hence option 3 is incorrect.

Option(4) They readily form compounds with halogens due to their electronegativity difference. Hence option 4 is incorrect.
