Answer:
b. The classical model defines how managers should make decisions, whereas the administrative model defines how managers actually make decisions.
Explanation:
The classical model of decision making is a strategic process which assumes that managers (decision makers) are well furnished with large amounts of information and as such are able to practically process the information for decision making.
On the other hand, an administrative model of decision making is a strategic process which assumes that managers (decision makers) are usually rational in their decisions and as such are willing to consider fundamental factors, criteria and a set of alternatives before making their decisions.
Hence, the difference between the classical model of decision making and the administrative model of decision making is that the classical model defines how managers should make decisions, whereas the administrative model defines how managers actually make decisions.
