Final answer:
To let users access MuleSoft Composer without authorization, the OAuth Policy should be set to 'All users are pre-authorized'. This bypasses individual authorizations and admin settings.
Step-by-step explanation:
To allow users to access MuleSoft Composer without first authorizing it, you should specify the OAuth Policies setting as B). All users are pre-authorized. This setting ensures that every user within your organization can use MuleSoft Composer without going through the OAuth authorization process individually. Admin settings and self-authorization processes are bypassed, providing immediate access to the tool.
Please note that the choice of OAuth Policies may vary based on specific security and access control requirements within your organization. It's essential to align the OAuth Policies with your organization's security policies and user access needs when configuring access to MuleSoft Composer or any other platform.
