Explanation

Option A — Correct: UPI enables real-time transfer of money already held in bank accounts, whereas the Digital Rupee (e₹) is sovereign digital currency issued by the RBI and functions as legal tender.

Option B — Correct: UPI payments involve instant debit and credit of bank accounts. With e₹, the value is transferred directly between digital wallets, providing settlement finality similar to physical cash.

Option C — Correct: UPI transactions pass through bank accounts and therefore appear in bank statements. In e₹ transactions, wallet-to-wallet transfers do not ordinarily appear in bank statements; only loading or unloading the wallet is reflected.

Option D — Incorrect: UPI represents commercial bank money, making the respective bank liable. The Digital Rupee is a direct liability of the RBI, backed by the sovereign.

Therefore, Options A, B and C are correct, while Option D is incorrect.
