Explanation

Power Automate custom connectors natively support the following authentication types: No Auth, API Key, Basic Authentication, OAuth 2.0, Azure Active Directory (AAD), and Windows Authentication. Basic authentication (A) uses a username and password. Generic OAuth 2.0 (B) is a widely supported delegated authorization framework. API Key (D) passes a key in a header or query parameter. OpenID Connect (C) is an identity layer on top of OAuth 2.0 but is not listed as a distinct, selectable authentication type in the custom connector wizard - OAuth 2.0 covers this scenario. Pass-through (E) is not a supported authentication type for custom connectors.
