Q1. According to RBI's benchmarking of India's payment systems, which pair represents India's two fast payment systems facilitating instant funds transfers?
Explanation
IMPS and UPI are the two fast payment systems named by RBI for facilitating instant funds transfers. NEFT and RTGS are major funds-transfer systems but are not the pair identified in the cited fact as India's two fast payment systems. BBPS and AePS belong to adjacent digital-payment infrastructure, and RuPay with NACH is also a near-miss pairing rather than the cited instant-transfer pair.
