Among the following complexes (K-P) :
$K _3[Fe(CN _6]-K $ and $ [Co(NH _3) _6]Cl _3-L$ ;
$Na _3[Co(oxalate) _3]-M $ and $ [Ni(H _2O) _6]Cl _2-N$ ;
$K _2[Pt(CN) _4]-O$ and $[Zn(H _2O) _6](NO _3) _2 - P$;
the diamagnetic complexes are:

A
L,M,O,P
💡 Explanation:
$K _3[Fe(CN _6]-K $ = $ 3d^5$ it is paramagnetic
$ [Co(NH _3) _6]Cl _3-L$ = $3d^6$ is diamagnetic
$Na _3[Co(oxalate) _3]-M $ = $3d^6$ is diamagnetic
$ [Ni(H _2O) _6]Cl _2-N$ = $3d^8$ is paramagnetic
$K _2[Pt(CN) _4]-O$ = $d^3 $ it is diamagnetic
and $[Zn(H _2O) _6](NO _3) _2 - P$;= $ d^6$ it is diamagnetic
