An organic compound A has the molecular formula of `C_7H_6O`. When A is treated with NaOH followed by acid hydrolysis, it gives two products, B and C. When B is oxidised, it gives A. When A and C are each treated separately with `PCl_5`, they give two different organic products D and E.
Identify A to E.
