(C) To identify diamagnetic complexes,we check for the presence of unpaired electrons in the central metal ion:$(K)\ K_3[Fe(CN)_6]: Fe^{3+}$ is $d^5$. $CN^-$ is a strong field ligand,causing pairing. It has $1$ unpaired electron. (Paramagnetic)$(L)\ [Co(NH_3)_6]Cl_3: Co^{3+}$ is $d^6$. $NH_3$ is a strong field ligand,causing pairing. All electrons are paired. (Diamagnetic)$(M)\ Na_3[Co(ox)_3]: Co^{3+}$ is $d^6$. $ox^{2-}$ is a strong field ligand,causing pairing. All electrons are paired. (Diamagnetic)$(N)\ [Ni(H_2O)_6]Cl_2: Ni^{2+}$ is $d^8$. $H_2O$ is a weak field ligand. It has $2$ unpaired electrons. (Paramagnetic)$(O)\ K_2[Pt(CN)_4]: Pt^{2+}$ is $5d^8$. Strong field ligand $CN^-$ causes pairing in the $5d$ orbital. All electrons are paired. (Diamagnetic)$(P)\ [Zn(H_2O)_6](NO_3)_2: Zn^{2+}$ is $d^{10}$. All electrons are paired. (Diamagnetic)Thus,the diamagnetic complexes are $L, M, O,$ and $P$.

Identify the diamagnetic complexes among the following complexes $K$ to $P$:
$(K)\ K_3[Fe(CN)_6]$
$(L)\ [Co(NH_3)_6]Cl_3$
$(M)\ Na_3[Co(ox)_3]$
$(N)\ [Ni(H_2O)_6]Cl_2$
$(O)\ K_2[Pt(CN)_4]$
$(P)\ [Zn(H_2O)_6](NO_3)_2$
