An Account Group Membership Certification is designed to certify group memberships within accounts, typically focusing on the validation of access within specific account groups (e.g., Active Directory groups).

Since the bank's goal is to ensure that all roles include the correct entitlements, an Account Group Membership Certification is not suitable for this purpose.
Thus, the correct answer is B. No.
