Solution:
- PLAN This problem is based on concept of VBT and magnetic properties of coordination compound.
Draw VBT for each coordination compound.
If unpaired electron is present then coordination compound will be paramagnetic otherwise diamagnetic.
Coordination compounds of
A. MO EC for
Number of unpaired electrons
Magnetic properties
Geometrical isomers of
B.
Magnetic properties
Ionisation isomers of
C. MOEC of 
Magnetic property
Ionisation isomers are
and
D. MOEC of
Magnetic property
Geometrical isomers are
Trans
Thus, magnetic property and isomerism in given coordination compound can be summarised as
(P)
(Q)
(R)
(S)
Hence, (b) is the correct choice.
