Maybe D because PostgreSQL's native authentication can be set up with SSL certificates for password-less access, which works directly without relying on external identity providers.

Option A seems solid because IAM lets you use tokens instead of passwords, which fits password-less needs for both read and write without relying on external directories.

It’s B since Managed AD usually handles password-less SSO better for both read/write.

Maybe B. Managed Active Directory can enable single sign-on, which often means password-less access for apps integrated with AD. Could be a better fit for seamless read/write authentication.
