Correct Answer: (a) Mobile wallets will not be necessary for online payments.

Since its inception, UPI has transformed India's payment landscape, driving financial inclusion and creating a cashless economy. It enables a range of features, including instant transfers, QR code payments, and recurring transactions, making it a preferred choice for millions of users. UPI is also accepted for international merchant payments in seven countries including UAE, France, Singapore, etc.
