Choose the correct matching:
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-iii, c-i, d-iv
C
a-i, b-iv, c-ii, d-iii
D
a-iii, b-ii, c-i, d-iv
Correct Answer
Option A
Detailed Explanation
Chromium in Cr2O7^2– has an oxidation state of +6, sulfur in SO3^2– has +4, sulfur in SO4^2– has +6, and chromium in Cr^3+ has +3. This is corroborated by the oxidation number changes described in the provided NCERT context.
