The correct option is They let you reference one secret across multiple repositories so you avoid duplicating the same value.

Defining the token once at the organization scope allows many repositories to reference the same secret name in their workflows. You rotate the value in one place and every pipeline that uses it automatically picks up the change. This centralization reduces duplication, prevents drift across repositories, and simplifies auditing and access management.

They restrict secret visibility to repository administrators only is incorrect because access is not limited to administrators. Workflows can consume the secret based on repository and organization policies, and owners can scope availability to selected repositories rather than only to admins.

They are intended to hold public configuration values that are not sensitive is incorrect because secrets are for sensitive values. Non sensitive settings should use variables or committed configuration instead.

They can be created only for personal accounts and are not available to organizations is incorrect because organizations can create and manage secrets that are usable by one or many repositories.
