Answer:
c. actions followed by pleasurable consequences are more likely to occur
Explanation:
The law of effect by Edward Thorndike states that responses that produce a pleasurable consequence in a particular situation are more likely to occur again in that situation, and responses that produce a punishment or pain are less likely to occur again in that situation. This law was made in 1905 and it suggests that actions are based on consequences that might have occurred in the past.
Most economists consider 5% to be acceptable.
