Option (i) is the correct answer
Let the oxidation number of central atom be 'y'.
Oxidation number of O = −2
CrO2−: y + 2 × (−2) = −1
y − 4 = −1 or y = +3
CrO42−? : y + 4 × (−2) = −2
y − 8 = −2 or y = +6
ClO3−: y + 3 × (−2) = −1
y − 6 = −1 or y = +5
MnO4−: y + 4 × (−2) = −1
y − 8 = −1 or y = +7
increasing order of oxidation number of the central atom is:
CrO2 – , C
