Why Correct: The Damodar Valley Corporation (DVC), established on 7 July 1948, was modeled after the Tennessee Valley Authority (TVA) of the United States for integrated river valley development.
Distractor Analysis: AFC is not a recognized foreign river valley project. DDC is not a standard abbreviation for any major foreign planning project. 'None of the above' is incorrect because TVA was explicitly the model.
Takeaway: Other major river valley projects in India include Bhakra Nangal (modeled after US Bureau of Reclamation) and Hirakud (first major multipurpose project post-independence).
