Correct Option: B

In terms of Section 22 of the Reserve Bank of India Act, the RBI has been given the statutory function of note issue on a monopoly basis. The note issue in India was originally based upon “Proportional Reserve System”. When it became difficult to maintain the re-serve proportionately, it was replaced by “Minimum Reserve System “. According to the RBI Amendment Act of 1957, the bank should now maintain a minimum reserve of Rs.200 crore worth of gold coins, gold bullion and foreign securities of which the value of gold coin and bullion should be not less than Rs.115 crore.
