In a sharing model, which group is created to manage associated record access dynamically?

The correct choice is sharing rules. Sharing rules are specifically designed to give users access to records that they do not own with the intent of sharing the data dynamically based on criteria set up by the Salesforce administrator.

When you create sharing rules, you can define conditions under which certain records are shared with users or groups of users, thereby enhancing collaboration and ensuring that appropriate access is granted based on business requirements. For instance, if a specific type of record should be visible to a larger audience for collaboration purposes, sharing rules enable this by moving beyond the constraints of role hierarchies and ownership.

Role hierarchies serve to define what users can see based on their position within the organization, while public groups are collections of users that can simplify the sharing process but do not manage access dynamically in response to changing conditions. Queues are primarily used to organize and manage workloads for records but are not designed for broader access management. Hence, sharing rules are the most appropriate mechanism when the goal is to manage record access dynamically.
