Statement C is the only wrong statement because even with digital payment systems, robust cybersecurity measures remain essential. UPI does support instant mobile-based transfers, digital wallets store card details or balances and PoS terminals accept card and mobile payments, so A, B and D are correct. Cyberattacks, fraud and phishing continue to be threats, so it is misleading to say that cybersecurity is no longer needed. Hence the option that selects only C as wrong is correct.
Option A:
Option A is incorrect because it treats both A and C as wrong statements. Statement A is accurate and describes a core feature of UPI as used in India. Grouping a true statement with a false one makes this combination invalid.
Option B:
Option B is correct because it isolates C as the single wrong statement and implicitly accepts A, B and D as correct. It reflects the reality that digital payment systems still require encryption, authentication and user awareness for safe use.
Option C:
Option C is incorrect because it considers both C and D as wrong. While C is false, D correctly recognises that PoS terminals support card and mobile-based payments. Including a true statement in the wrong set makes the option unacceptable.
Option D:
Option D is incorrect because it takes B and C as wrong statements. B is true since digital wallets commonly store card details or balances for easy transactions. Combining this true statement with the false claim in C produces a logically inconsistent option.
