Which of the following is not an Indo-Nepal Cooperation Project?

The Sharda Barrage, Tanakpur Barrage, and Pancheshwar Project are all integral components of the 1996 Mahakali Treaty between India and Nepal [t1][t4]. This treaty focuses on the integrated development of the Mahakali River, which forms a boundary between the two nations [t4][t5]. Specifically, the Pancheshwar Multipurpose Project is considered the centerpiece of this bilateral cooperation [t2][t3]. In contrast, the Chukha (or Chukka) Hydropower Project is a major cooperation project between India and Bhutan, not Nepal [c2][t7]. India provided technical and financial assistance for the Chukha project, and it remains a significant source of power export from Bhutan to India [t7]. Therefore, the Chukka Project is the only option that does not involve Indo-Nepal cooperation.
