X₃Y₂ (i = 5) when reacted with A₂B₃ (i = 5) in aqueous solution gives brown colour. These are separated by a semipermeable membrane AB as shown. Due to osmosis there is:

• A

  Brown colour formation in side X

• B

  Brown colour formation in side Y

• C

  Formation in both of the sides X and Y

• D

  No brown colour formation
