Which of the following payment methods are allowed if using a post-pay threshold?

The selected answer options are correct because PayPal, Debit card, and Credit card are all allowed payment methods when using a post-pay threshold in Microsoft Advertising. With post-pay billing, advertisers are billed for their ad spend after reaching a certain threshold, and the available payment methods for this system include PayPal, debit cards, and credit cards. These options allow for easy and flexible payments once the threshold is met, providing advertisers with the ability to fund their campaigns and settle payments through these commonly accepted methods. Checks, however, are not a typical payment method supported for post-pay threshold billing in Microsoft Advertising, making it the incorrect choice. The inclusion of PayPal, debit cards, and credit cards ensures that advertisers have multiple convenient options for payment, making it easier to manage and fund their advertising campaigns.
