Step 1: Understand Liquidity Adjustment Facility (LAF).
LAF is a monetary policy tool used by central banks to manage short-term liquidity in the banking system. In India, the Reserve Bank of India (RBI) uses LAF to absorb or inject liquidity. The two key instruments under LAF are the Repo Rate and Reverse Repo Rate.
Step 2: Evaluate each option.
Option (A): Incorrect, Call Money Rate and Mumbai Inter-bank Offered Rate are not part of LAF instruments.
Option (B): Correct, LAF uses Repo Rate (the rate at which the RBI lends to commercial banks) and Reverse Repo Rate (the rate at which banks park excess funds with RBI).
Option (C): Incorrect, Bank Rate and Statutory Liquidity Ratio (SLR) are not part of LAF instruments.
Option (D): Incorrect, Cash Reserve Ratio (CRR) and Prime Lending Rate are not related to LAF instruments.
Thus, the correct answer is (B).
