Which billing options are available with LinkedIn Advertising? Select all that apply.

LinkedIn Advertising offers several flexible billing options to suit different business needs. Credit card is a standard and widely available payment method, allowing for immediate payment and campaign launch. Monthly invoicing is an option for eligible advertisers, typically larger businesses or agencies with established credit, providing a consolidated bill for their advertising spend. An insertion order (IO) is a formal, legally binding contract between an advertiser and LinkedIn, often used for larger campaigns or when specific terms and conditions need to be outlined beyond standard online agreements. "None of these" is incorrect because multiple billing options are indeed available.
