领英广告提供哪些结算选项？请选择所有合适选项。

LinkedIn Ads offers several flexible billing options to suit different advertiser needs. "广告订单" (Ad Order) refers to a direct billing arrangement, often used by larger organizations or agencies with established credit, allowing for invoicing and payment terms. "信用卡" (Credit Card) is a common and convenient payment method for most advertisers, especially small to medium-sized businesses, enabling immediate payment and automatic charges. "月度结算" (Monthly Invoicing) is another option, typically available to advertisers who meet specific spending thresholds and credit requirements, allowing them to pay for their ad spend on a monthly basis after an invoice is issued. These three options cover the primary ways advertisers can pay for their campaigns on LinkedIn. "以上均不是" (None of the above) is incorrect because LinkedIn Ads clearly provides these billing methods.
