This option fits the scope for the minimum lovable product (MLP) based on Pega best practices. An MLP is the smallest version of an application that delivers value to customers and stakeholders while meeting their core needs and expectations. Pega best practices suggest that you should focus on building an MLP that solves one problem well, provides immediate feedback, and creates positive emotions for users.

To satisfy this requirement, you need to create a service level that specifies both A and B options. A service level is a rule that defines time intervals and actions for completing an assignment or resolving a case. A service level has two components: goal and deadline. The goal defines when an assignment or case should be completed ideally, while the deadline defines when an assignment or case must be completed at latest. You can also configure actions to perform at each component, such as sending notifications, escalating urgency, etc. Reference: https://community.pega.com/knowledgebase/articles/case-management/86/configuring-service-levels
