AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
Answer: C
Assertion (A) is true — informal lenders charge much higher interest rates than formal lenders. Reason (R) is false — the RBI supervises only formal sector lenders (banks, cooperatives); there is no organisation that supervises informal lenders.
The passage clearly states: "The Reserve Bank of India supervises the functioning of formal sources of loans" and "There is no organisation which supervises the credit activities of lenders in the informal sector." So R incorrectly claims RBI regulates informal lenders — making R false. Since R is false, the answer is C.
