Answer:

The correct option is A, [Cr(NH3)6]2 [NiF6]3.

Explanation:

In the complex [Cr(NH3)6]2 [NiF6]3, the oxidation state of nickel is +3.

Reasoning:

Option A: [Cr(NH3)6]2 [NiF6]3

- The oxidation state of chromium is +3, as it is in the form of [Cr(NH3)6]3+.
- The oxidation state of nickel is +3, as it is in the form of [NiF6]3-.
- Therefore, the oxidation state of nickel is highest in this complex.

Option B: [Ni(NH3)6][BF4]2

- The oxidation state of nickel is +2, as it is in the form of [Ni(NH3)6]2+.
- Therefore, the oxidation state of nickel is lower in this complex compared to option A.

Conclusion:

Thus, the correct option is A, [Cr(NH3)6]2 [NiF6]3, where nickel is in the highest oxidation state.
