B
In ${K_3}[Fe{(CN)_6}],$ the ligand has satisfied both primary and secondary valencies of ferric ion.
C
In $[Cu{(N{H_3})_4}]S{O_4},$ the ligand has satisfied only the secondary valency of copper.
✓
Both $(a)$ and $ (c)$

✓

Answer

Correct option: D.

Both $(a)$ and $ (c)$

d
(d) In ${K_3}[Fe{(CN)_6}]$ the ligand are negative which is present in coordination spheres shows a dual behaviour. It may satisfied both primary & secondary valencies while neutral ligand satisfied only secondary valencies.
