Explanation:

"The lowest energy configuration for an atom is the one having the maximum number of unpaired electrons allowed by thePauli principle in a particular set of degenerate orbitals" is known as Hund's rule.

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;
