Compounds A, B, C and D are solid trihalides, all containing the same central atom. Compounds A, B and C are pale lilac (pale purple) in colour but compound D is dark green. Compound A is insoluble in water and alcohol but the rest of the three are soluble in both the solvents. The correct statement indicating the central atom and halides present in each of the compounds is

A

Central atom is As and the halides are fluoride, chloride, bromide and iodide respectively

B

Central atom is Co and the halides are fluoride, chloride, bromide and iodide respectively

C

Central atom is Cr and the halides are fluoride, chloride, bromide and iodide respectively

D

Central atom is Nd and the halides are fluoride, chloride, bromide and iodide respectively
