Answer: Option B, Reduced

Explanation:

Since oxidation number of Ni in Ni+2 is + 2 and it is reduced to + 1 and zero by gaining of Electrons.

2 moles of Ni+2 reduced from+2 to + 1

state by gaining of 1 electron per each mole and another mole of Ni+2 reduced from + 2 zero oxidation state by gaining of 2 electrons
