Q. Which river is linked to the Sukta irrigation project?
Answer: Narmada
Notes: The Sukta irrigation project utilizes water from the Narmada River, irrigating about 6,200 hectares. The Narmada is one of India's major rivers, housing several significant irrigation projects. Tawa, Sindh, and Wainganga rivers are associated with other projects, but not with Sukta. This direct river-project linkage defines the correct answer as Narmada.
