Which of the following is a correct decreasing order? 

Answer: [B] Marginal Standing Facility >Repo Rate >Reverse Repo Rate

Difference between Repo Rate and MSF is 200 Basis Points.  So, Repo rate will be in the middle, the Reverse Repo Rate will be 100 basis points below it, and the MSF rate 100 bps above it. Thus, if Repo Rate is X%, reverse repo rate is X-1% and MSF is X+1%.
