A new AWS Organization has SCPs enabled but no custom policies yet. What is the default permission state for member accounts?
A. AWS automatically attaches the FullAWSAccess SCP to the root, which allows all actions on all resources — member accounts retain full access governed only by their own IAM policies.
B. Member accounts have no permissions by default until an administrator explicitly creates and attaches an allow-list SCP that specifies permitted services.
C. The management account's IAM policies automatically propagate to all member accounts, granting the same level of access as the management account administrator.
D. All member accounts default to read-only access across all AWS services until a custom SCP explicitly grants write permissions to each OU.
