An alkene 'A' (molecular formula `C_(5)H_(10)`) on ozonolysis gives a mixture of two compounds 'B' and 'C'. Compound 'B' gives positive Fehling's test and also forms iodoform on treatement with `I_(2)" and "NaOH`. Compound 'C' does not give Fehling's test but forms iodoform. Identify the compounds A, B and C. Write the reaction for ozonolysis and formation of iodoform from B and C.

A

`{:(" X"," Y"," Z"),(C_(6)H_(5)COCH_(3),CH_(3)CHO,CH_(3)COCH_(3)):}`

B

`{:(" X"," Y"," Z"),(CH_(3)-CH=underset(CH_(3))underset(|)C-CH_(3),CH_(3)CHO,CH_(3)COCH_(3)):}`

C

`{:(" X"," Y"," Z"),(CH_(3)CH_(2)CH=CH_(2),CH_(3)CH_(2)CHO,HCHO):}`

D

`{:(" X"," Y"," Z"),(CH_(3)-CH=CH-CH_(3),CH_(3)CHO,CH_(3)CHO):}`
