A

Square planar geometry and paramagnetic

B

Tetrahedral geometry and diamagnetic

C

Square planar geometry and diamagnetic

D

Tetrahedral geometry and paramagnetic

Solution:

As CO is a strong field ligand so configuration would be

n=0(no unpaired electron)
For, four ‘CO’-ligands hybridisation would be and thus the complex would be diamagnetic and of tetrahedral geometry as follows.
