创建广告帐号需要什么？请选择三个答案。

To create an ad account on LinkedIn, you need a personal LinkedIn profile to serve as the account owner and administrator. You also need "Paid Media Admin" permissions for the associated Company Page, as this role grants the necessary authority to manage advertising campaigns for that organization. Finally, a valid payment method is essential to fund your advertising efforts and launch campaigns. While "Page Admin" permissions for the Company Page are important for general page management, "Paid Media Admin" specifically enables ad account creation and management.
