Matach column I with column II related to the figure given below and then select the appropriate option from the codes given

Options

A. `{:(A,B,C,D),(2,1,3,2):}`
B. `{:(A,B,C,D),(2,3,1,2):}`
C. `{:(A,B,C,D),(1,2,1,3):}`
D. `{:(A,B,C,D),(1,2,3,1):}`

Answer

D

Explanation

Given figure represents the corrosions of iron in the atmosphere oxidation occurs atanode and reduction occurs at cathode
at cathode `O_(2)+4H^(+) (aq)+4e^(-) rarr 2H_(2) O(ll)E_(H^(+))^(@)|_(2)|H_(2)O)=1.23 V`
overall reaction
`2Fe(s) _+O_(2) (g) +4H^(+) (aq) rarr 2Fe^(2+) (aq)+2H_(2)O(I)E_(cell)^(@)=1.67 V`
