2. An Oh XY6 molecule exhibits two Tru, IR active modes. Which statement is true? (A) Each Tiu mode is triply degenerate, and each gives rise to one absorption in the IR spectrum of XY6 (B) Each Tiu mode is triply degenerate, and each gives rise to three absorptions in the IR spectrum of XY6 (C) Each Tlu mode is non-degenerate, and gives rise to one absorption in the IR spectrum of XY6 (D) One of the Tiu modes is the symmetric stretching mode of XY6
