 Context: The bank wants to suppress mortgage offers if a customer ignores three offers within a group for one month.

 Suppression Rule: In Pega, suppression rules are defined to manage overexposure to customers.

 Implementation: The suppression rule should be set at the group level to ensure the entire group of mortgage actions is suppressed for 30 days after three rejections.

 Pega Configuration: The configuration for suppression rules supports this requirement by allowing the setting of a threshold for rejections across any channel, thus making option A the correct choice​​.
