Match List-I with List-II and select the correct answer using the codes given below the lists :

Options

A. `{:(P,Q,R,S),(1,3,2,4):}`
B. `{:(P,Q,R,S),(3,2,4,1):}`
C. `{:(P,Q,R,S),(4,3,2,1):}`
D. `{:(P,Q,R,S),(4,1,2,3):}`

Answer

C

Explanation

`1 to IO_(3)^(-)+SO_(2) to I_(2) +SO_(4)^(2-)`
`I_(2)+"Starch" to "deep blue colour"`
`2 to SO_(2)+MnO_(4^(-)) to underset("colourless")(MnSO_(4))+SO_(4)^(2-)`
`3 to Zn+NaOH + SO_(2) to underset("rotten egge smell")(H_(2)Suarr+Zn^(2+))`
`4 to CO_(2) +Ca(OH)_(2) to CaCO_(3)darr ("milky")`
