In the post-reform period (after 1991), the CRR (Cash Reserve Ratio) has been reduced in stages by the RBI as part of financial liberalization and to increase lendable resources for banks. This was done to improve monetary policy flexibility and banking sector efficiency. Option A is incorrect as bank rate hasn't been fixed at 10%. Option B is incorrect as CRR has been reduced, not increased to 8%. Option D is incorrect as banks can raise funds from multiple sources, not just private resources.
