Carolyn 可以在营销管理工具中编辑和添加新广告素材。她具有什么权限？请选择所有合适选项。

Carolyn can edit and add new creatives because several roles grant this permission. As an Account Administrator, she has full control over the ad account, including creative management. A Campaign Administrator can manage all aspects of campaigns, which includes creating and editing ad creatives. A Creative Administrator is specifically designed for this task, allowing them to add, edit, and manage all creatives within the account. Finally, a Billing Administrator, while primarily focused on financial aspects, often has broad permissions that extend to campaign and creative management to ensure campaigns can run effectively. A 'Visitor' role would only allow viewing, not editing or adding creatives.
