Explanations:The interlinking of rivers is a significant initiative in India aimed at addressing water scarcity and improving agricultural productivity by transferring water from water-surplus regions to water-deficient regions. The Kosi-Mechi project is one such interlinking project that has been approved by the Union government for the state of Bihar.
The Kosi and Mechi rivers are both located in the northeastern part of India, with the Kosi originating in Nepal and flowing through Bihar, and the Mechi also originating in Nepal and flowing through Bihar and West Bengal. The interlinking project aims to transfer water from the Mechi river to the Kosi river basin, which is known to face significant water scarcity issues, particularly during the dry season.
The project is expected to benefit a large agricultural area in Bihar by providing a more reliable water supply, which can enhance crop yields and support the livelihoods of farmers in the region. The Union government has allocated a significant amount of funds, 4900 crore, for the implementation of this project, highlighting its importance and the potential benefits it can bring to the state.
It is crucial to understand the geographical context of the rivers and the state in which the project is being implemented. The Kosi and Mechi rivers are not located in Madhya Pradesh, Jharkhand, or Punjab, which are the other options provided. Therefore, the correct answer is Bihar, as the project is specifically designed to address the water needs of this state.
