The correct answer is API Key, Account ID, and Region.

The API Key is provided with each request so the service can authenticate the caller and apply any usage limits or permissions tied to that key.

The Account ID identifies the customer account or tenant so the request is routed to the correct owner and billing context within the service.

The Region selects the geographic endpoint and runtime location so requests are sent to the appropriate regional backend and any region specific resources are used.

Project ID is typically a separate cloud project identifier and it is not the value required here when the service expects an account level identifier.

Endpoint URL is not something you must manually specify in this console flow because the chosen Region is used to determine the endpoint automatically.

Subscription Key is a term used by other platforms and it is not the authentication mechanism required here when an API Key is used.

OAuth Client Secret is only used when performing OAuth flows to obtain bearer tokens and it is not required for simple key based access.
