Option 1 -> Places CRR first, but CRR is typically the lowest among these rates.
Option 2 -> Incorrectly places CRR at the top and reverses the order of Reverse Repo and Repo rates.
Option 3 -> Correctly arranges: SLR (highest at 18-19%), Repo Rate (6-6.5%), Reverse Repo Rate (~3.35-6%), and CRR (lowest at ~4-4.5%).
Option 4 -> Incorrectly starts with Reverse Repo Rate which is not the highest rate.
Hence, Option 3: (D), (B), (C), (A) -> The descending order is: Statutory Liquidity Ratio (SLR) maintains the highest rate around 18-19% as banks must maintain this percentage of deposits in liquid assets. Repo Rate (the rate at which RBI lends to banks) comes next at around 6-6.5%. Reverse Repo Rate (the rate at which RBI borrows from banks) is slightly lower than Repo Rate. Cash Reserve Ratio (CRR) is the lowest, typically around 4-4.5%, representing the percentage of deposits banks must keep with RBI in cash. -> correct
