For an inverse spinel, $\mathrm{AB_2O_4}$, the A and B, respectively, can be

(a)Ni(II) and Ga(III)

(b)Zn(II) and Fe(III)

(c)Fe(II) and Cr(III)

(d)Mn(II) and Mn(III)

Answer

Answer: A ✓ checked by 4AB · confidence high

Explanation

NiGa₂O₄ is inverse: Ni²⁺ (d⁸, strong octahedral preference) takes octahedral sites, Ga³⁺ (d¹⁰) splits between sites (a).
