Give below are two statements: One is labelled as Assertion A and the other is labelled as Reason R: Assertion A: The stability order of +1 oxidation state of Ga\mathrm{Ga}Ga, In and Tl\mathrm{Tl}Tl is Ga Reason R: The inert pair effect stabilizes the lower oxidation state down the group. In the light of the above statements, choose the correct answer from the options given below:
  1. A
    A is true but R is false.
