Platform Administrator is correct because that role provides access to the billing and subscription management page in the admin portal.

Platform Administrator is an instance or site level role that includes permissions to view and manage invoices, subscriptions, and account wide billing settings. Users with this role can open the billing and subscription pages and make subscription changes and payment updates as needed.

Both Platform Administrator and Jira Administrator is incorrect because billing access is granted to the Platform Administrator only and not to the Jira Administrator, so naming both is not accurate.

Jira Administrator is incorrect because that role focuses on product and project configuration within Jira and does not include account wide billing or subscription management permissions.

Project Administrator is incorrect because project administrators are limited to individual project settings and they do not have rights to access billing or subscription pages at the platform level.
