# In coordination chemistry, the donor atom of a ligand is

$\begin{array}{1 1}(a)\;\text{a Lewis acid}\\(b)\;\text{the counter ion}\\(c)\;\text{the central metal atom}\\(d)\;\text{the atom in the ligand that shares an electron pair with the metal}\end{array}$

In coordination chemistry, the donor atom of a ligand is the atom in the ligand that shares an electron pair with the metal
Hence (d) is the correct answer.
