Answer
B: Reduction
Explanation
This equation involves nickel in an oxidation state of +3 (Ni^3+) gaining one electron (e^-) to transition to an oxidation state of +2 (Ni^2+). In chemistry, the process of gaining electrons is referred to as 'reduction'. This occurs because the overall oxidation number is reduced—the number decreases from +3 in Ni^3+ to +2 in Ni^2+. Hence, this is a reduction reaction.
