Expert Answer
(a) A ligand is an ion or molecule, which donates a pair of electrons to the central metal atom or ion to form a coordination complex. Strong field ligands have large Δ. They are π-acceptor ligands. They have the tendency of pairing of electrons of the metal ions.
 
(b)Fig A is weak ligand because weak ligand can't do pairing.
 
(c) Ions of transition metals are colured due to presence of free unpaired electrons.
