The correct option is Jira Administrator product admin role.

Jira Administrator product admin role grants the product level administration needed to create and manage product roles and to set a default group for a role in a Jira Cloud product. This role gives the necessary access to Jira product settings where role definitions and default group assignments are configured so Alex can add a new product role and assign its default group.

Project Administrator is incorrect because a project administrator only manages settings within a single project and does not have the global product level permissions required to create new product roles or set role default groups across the Jira product.

Site Administrator is incorrect because site administration covers site wide tasks such as billing and user provisioning and does not automatically grant the Jira product administration rights needed to manage product roles unless the person is also granted the Jira product admin role.

Jira Software user role is incorrect because that role only provides access to use Jira Software and it does not include administrative privileges to create product roles or change default group assignments.
