An organic compound 'X' C(8)H(8)O forms ...

An organic compound 'X' `C_(8)H_(8)O` forms an orange-red precipitate of 2, 4-DNP and gives yellow precipitate with iodine and aqueous sodium carbonate on heating. It neither reduces Tollens or Fehlings reagent, nor does it decolourise bromine water or Baeyers reagent. On drastic oxidation wtih chromic acid, it gives a carboxylic acid 'Y' `(C_(7)H_(6)O_(2))`. Compounds X and Y are

A

B

C

D

`CH_(2)=CH-C-=C-CH=CH-overset(O)overset(||)(C)-CH_(3)&CH_(2)=CH-C-=C-CH=CH-COOH`
