The compound 'A' is a colourless solid. It gives following tests: Test-I: The addition of compound 'A' solution to a solution of KI, followed by acidification with dilute H_(2)SO_(4), results in the formation of brown coloured compound 'B'. Test-II: The acidified KMnO_(4) solution is decolourized, by a solution of compound 'A', but no gas is evolved. Which of the following reaction(s) is/are correctly matched about Test-I and Test-II?
