Which of the following is a form of payment businesses commonly accept?

Businesses commonly accept cash as a form of payment due to its universal acceptance and ease of use. Cash transactions allow for immediate payment without the need for electronic processing, making it simple for both the business and the customer. It is widely trusted and recognized, providing a straightforward method for customers to purchase goods and services.

While gift cards are also a valid form of payment, they are not as universally accepted as cash. Gift cards are typically limited to certain retailers or brands and require prior purchase, which does not apply to all business transactions. Barter exchanges involve trading goods or services without money changing hands, which is less common and not a standard payment method for most businesses. Cryptocurrency, though gaining popularity, is still not widely accepted across all sectors, limiting its use as a primary payment method compared to cash, making cash the most conventional and readily accepted option.
