Option 1 -> This refers to open market operations, not specifically the repo rate mechanism.
Option 2 -> Repo Rate is the rate at which commercial banks borrow from the central bank by selling securities with an agreement to repurchase.
Option 3 -> This refers to the Reverse Repo Rate, where banks park their surplus funds with the central bank.
Option 4 -> This describes general lending by commercial banks, not the repo rate mechanism.
Hence, Option 2: Commercial banks can take loans from the central bank -> The Repo Rate (Repurchase Rate) is the interest rate at which the central bank lends money to commercial banks against government securities. Banks sell securities to the central bank with an agreement to repurchase them at a future date. It is a key monetary policy tool used to control liquidity and inflation in the economy. When repo rate increases, borrowing becomes expensive, reducing money supply, and vice versa. -> correct
