Solution

The correct option is D (i) Ligands, (ii) Ionisation sphere, (iii) Coordination number, (iv) Central atom
Ammonia is a ligand. It donates lone pair of electrons to Cobalt (central metal atom) and forms co-ordinate bond.

Co-ordination number is 6 as 6 ammonia ligand coordinate to central metal.

(ii) represents ionisation sphere , $[C o (N H_{3})_{6}]$ has $+ 3$ charge.

Hence ,option D is correct.
