Step 1: Understanding the Concept:
Institutional agricultural credit flow in India exhibits marked inter-regional and interstate disparities.
Step 2: Detailed Explanation:
According to RBI and NABARD credit flow reports:
- Southern states (e.g., Tamil Nadu, Andhra Pradesh, Karnataka) account for a disproportionately large share ($> 40\%$) of total ground-level agricultural credit disbursement (Statement B is true).
- Eastern and North-Eastern states receive an exceptionally low share ($< 10\text{--}12\%$) of formal institutional farm credit (Statement A is true).
- Credit is highly skewed and not uniformly distributed (Statement C is false).
- Western states (Maharashtra, Gujarat) have robust institutional credit networks (Statement D is false).
Step 3: Final Answer:
Hence, statements A and B only are true.
