Best Study for Sharing and Visibility Designer Exam

Hi there,I found following question on some blog.Do you think which one is correct?I think D is correct rather than C.Because to share a record to a specific Role, we should use public group that contain that role and turn off [Grant Access Using Hierarchies] on public group.

Universal Containers has a private sharing model on Accounts. Apex Managed Sharing is required to share certain account records with all users who are assigned to a specific Role in the Role Hierarchy. What should be the recommended way for the Architect to implement this?

• A. Create an AccountShare record associated to a public group containing the Users in the Role.
• B. Create an AccountShare record associated to each user who is assigned to the Role.
• C. Create an AccountShare record associated to the required Role.
• D. Create an AccountShare record associated to a public group containing the Role.
