Q1. Which of the following is the most likely consequence of implementing the Unified Payments Interface (UPI)?
A FDI inflows will drastically increase.
B Mobile wallets will not be necessary for online payments. Correct
C Direct transfer of subsidies to poor people will become very effective.
D Digital currency will totally replace the physical currency in about two decades.
Explanation
UPI enables bank-to-bank digital payments through interoperable payment addresses and apps, so a separate mobile wallet balance is not necessary for online payments. A sharp rise in FDI is not a direct consequence of this payment interface. Direct Benefit Transfer may benefit from digital rails, but UPI itself is not the main subsidy-transfer architecture. The complete replacement of physical currency by digital currency within about two decades is an extreme prediction, not the likely immediate implication of UPI.
