Clever enough to edit your post :D
And i guess you pasted the wrong question? It should K2Cr2O7 not KMnO4 :D
If its dichromate then it will be B. SO2 is a reducing agent and it will change the colour of Dichromate to green. KI is a reducing agent itself so no change in colour!

If the volume is increased, concentration must decrease and therefore rate will decrease.
I guess :p
