Source: Multi-purpose River Projects and Integrated Water Resources Management, Chapter 3
The textbook explicitly states: "The Krishna-Godavari dispute is due to the objections raised by Karnataka and Andhra Pradesh governments regarding the diversion of more water at Koyna by the Maharashtra government for a multipurpose project." Options C and D mention incorrect states and structures; Option A wrongly blames Andhra Pradesh. Always quote/paraphrase the textbook box directly for such factual MCQs.
