Exposing CrO3 to hydrogen chloride gas gives a red-vapor of compound P. When P is passed through a dilute solution of NaOH, it turns yellow due to the formation of complex ion Q. Adding acidified H2O2 to a solution of Q results in a dark blue compound R.
The option containing the correct structures of P, Q and R, respectively, is
