$\mathrm{MnCr}_{2} \mathrm{O}_{4}$ is likely to have a normal spinel structure because
(a)$\mathrm{Mn}^{2+}$ will have a LFSE in the octahedral site whereas the Cr will not
(b)Mn is $^{2+}$ oxidation state and both the Cr are in $^{3+}$ oxidation state.
(c)Mn is $^{3+}$ oxidation state and 1 Cr is in $^{2+}$ and the other is in $^{3+}$ state.
(d)$\mathrm{Cr}^{3+}$ will have a LFSE in the octahedral site whereas the $\mathrm{Mn}^{2+}$ ion will not.
