The correct answer is A. The Sone River valley (part of the Son-Mahanadi coalfield) is well-known for significant coal deposits in India, particularly in areas like Singrauli and Sohagpur.
Coal deposits in India are primarily concentrated in river valleys, particularly those of the Gondwana system.
Major coal-producing river valleys in India include the Damodar Valley, Mahanadi Valley, Son Valley, Godavari Valley, and Wardha Valley. The Alaknanda, Chambal, and Yamuna river valleys are not significant coal-producing regions.
