Column $II \ ($Isomerism$)$
$a.$
$\ce{[Co(NH_3)_4C_{l2}]^+}$
$4.$
 Geometrical
$b.$
$\ce{cis-[Co(en)_2Cl_2]^+}$
$1.$
Optical
$c.$
$\ce{[Co(NH_3)_5 (NO_2)]Cl_2}$
$2.$
Ionisation
$d.$
$\ce{[Co(NH_3)_6][Cr(CN)_6]}$
$3.$
Coordination
Isomerism in coordination compound is decided by type of ligands and geometry of coordination and arrangement of ligands.
  1. $\ce{[Co(NH_3)_4Cl_2]+}$ shows geometrical isomerism due to presence of two types of ligand whose $\ce{[Co(NH_3)_4Cl_2]+}$ arrangement around central metal ion.
  1. $\ce{cis-[Co(en)_2Cl_2]+}$ shows optical isomer due to its non-superimposable mirror image relationship.
  1. $\ce{[Co(NH_3)_5(NO_2)]Cl_2}$ shows ionization isomer due to its interchanging ligand from outside the ionization sphere.
  2. $\ce{[Co(NH_3)_6][Cr(CN)_6]}$ shows coordination isomer due to interchanging of ligand in between two metal ions from one coordination sphere to another coordination sphere.
Hence, correct choice is $(d).$

After watching a programme on TV about the presence of carcinogens (cancer causing agents) Potassium bromate and Potassium iodate in bread and other bakery products, Rupali a Class XII student decided to make others aware about the adverse effects of these carcinogens in foods. She consulted the school principal and requested him to instruct the canteen contractor to stop selling sandwiches, pizzas, burgers and other bakery products to the students. The principal took an immediate action and instructed the canteen contractor to replace the bakery products with some protein and vitamin rich food like fruits, salads, sprouts, etc. The decision was welcomed by the parents and the students.
