The geometries of the ammonia complexes of

N i^{2 +}, P t^{2 +} a n d Z n^{2 +}

respectively, are :

Octahedral, square planar and tetrahedral

square planar, octahedral and tetrahedral

tetrahedral, square planar and octahedral

octahedral , tetrahedral and square planar

Solution:

Metal ion	Complex with $N H_{3}$	Geometry
$N i^{2 +}$	${[N i {(N H_{3})}_{6}]}^{2 +}$	Octahedral
$P t^{2 +}$	${[P t {(N H_{3})}_{4}]}^{2 +}$	Square planar
$Z n^{2 +}$	${[Z n {(N H_{3})}_{4}]}^{2 +}$	Tetrahedral

So, option octahedral, square planar and tetrahedral order is correct.
