An organic compound `(A) (C_5 H_8 O_3)` on heating with soda lime gives `(B)` which reacts with `HCN` to give `( C)`. The compound `( C)` reacts with thionyl chloride to produce `(D)` which on reaction with `KCN` gives a compound `( E)`. Alkaline hydrolysis of `( E)` gives a salt `(F)` which on heating with soda lime produces `n-butane`. Careful oxidation of `(A)` with dichromate give acetic acid and malonic acid. Give the structures to `(A)` to `(F)` with proper reasoning.
