(A) $1$. $H$ atom: $1s^1$ (Paramagnetic)$2$. $NO_2$ monomer: Odd electron (Paramagnetic)$3$. $O_2^{-}$ (superoxide): $13$ electrons (Paramagnetic)$4$. $S_2$ (vapour): Similar to $O_2$,has two unpaired electrons in $\pi^*$ orbitals (Paramagnetic)$5$. $Mn_3O_4$: Mixed oxide of $MnO \cdot Mn_2O_3$,contains $Mn^{2+}$ and $Mn^{3+}$ (Paramagnetic)$6$. $(NH_4)_2[FeCl_4]$: $Fe^{2+}$ is $d^6$ (Paramagnetic)$7$. $(NH_4)_2[NiCl_4]$: $Ni^{2+}$ is $d^8$ (Paramagnetic)$8$. $K_2MnO_4$: $Mn^{6+}$ is $d^1$ (Paramagnetic)$9$. $K_2CrO_4$: $Cr^{6+}$ is $d^0$ (Diamagnetic)Only $K_2CrO_4$ is diamagnetic. The total number of diamagnetic species is $1$.

Among the species given below,the total number of diamagnetic species is. . . . . $H$ atom,$NO_2$ monomer,$O_2^{-}$ (superoxide),dimeric sulphur in vapour phase,$Mn_3O_4$,$(NH_4)_2[FeCl_4]$,$(NH_4)_2[NiCl_4]$,$K_2MnO_4$,$K_2CrO_4$
