The correct option is 1 and 3 only because 'Commercial Paper' is indeed a short-term unsecured promissory note used for raising funds, primarily by companies, for working capital needs (Statement 1). 'Call Money' is a short-term borrowing and lending arrangement among banks, typically for a period of one day to two weeks, facilitating liquidity in the banking system (Statement 3). Conversely, Statement 2 is incorrect as 'Certificate of Deposit' is a short-term instrument issued by banks and not specifically by the Reserve Bank of India, while Statement 4 is also incorrect since 'Zero-Coupon Bonds' do not pay interest periodically but are sold at a discount and redeemed at face value, not specifically linked to scheduled commercial banks.
