The two isomers X and Y with the formula `Cr(H_(2)O)_(5)CIBr_(2)` were taken for experiment on depression in freezing point. It was found that one mole of X gave depression corresponding to 2 moles of particles and one mole of Y gave depression due to 3 moles of particels . The structural formulae of x and Y respectively are

Options

A. ` [Cr(H_(2)O)_(5)CI]Br_(2) , [Cr(H_(2)O)_(4)Br_(2)] CI.H_(2)O`
B. `[Cr(H_(2)O)_(5)CI]Br_(2),[Cr(H_(2)O)_(3)CIBr_(2)].2H_(2)O`
C. `[Cr(H_(2)O)_(5)Br]BrCI , [Cr(H_(2)O)_(4)CIBr] Br.H_(2)O`
D. `[Cr(H_(2)O)_(4)Br_(2)]CI.H_(2)O , [Cr(H_(2)O)_(5)CI]Br_(2)`
