What approach is China taking to maintain the acceptance of cash?

The correct answer is that China is mandating that payment groups hold cash deposits in non-interest-bearing accounts. This approach is a strategy to ensure that cash remains a viable option for transactions in the economy. By requiring payment service providers to maintain cash reserves, the government is reinforcing the importance of liquidity in the financial system and promoting the availability of cash for consumers.

This initiative helps to maintain consumer confidence in cash as a method of payment, ensuring that it does not diminish as digital payment systems grow in popularity. It acts as a safeguard against the potential risks of over-reliance on digital payment methods, particularly in a country where cash usage has been declining.

The other choices, while related to the overall theme of payments and cash in China, do not directly align with the government's current approach to sustaining cash acceptance. These alternative options suggest strategies that encourage or favor digital transactions instead of reinforcing cash's position in the market.
