An alkyl halide with molecular formula `C_6H_(13)Br` on dehyrohalogenation gives two isomeric alkenes X and Y with molecular formula `C_6H_(12)`. On reductive ozonolysis X and Y gives four compounds `CH_3COCH_3`, `CH_3CH_2CHO` and `(CH_3)_2CHCHO`. The alkyl halide is

Options

A. 4-bromo-2-methylpentane
B. 3-bromo-2-methylpentane
C. 2-bromo-2,3-dimethylbutane
D. 2,2-dimethyl-1-bromobutane
