Explanation:

Recently, the National Green Tribunal (NGT) has held that environmental clearance (EC) to Kaleshwaram Lift Irrigation Project (KLIP) was granted ex post facto, after completion of substantial work, by the Ministry of Environment, Forests and Climate Change (MoEF&CC) “in violation of law”.

• The Kaleshwaram Lift Irrigation Project is a multi-purpose irrigation project on the Godavari River in Kaleshwaram, Bhupalpally, Telangana.
• Its farthest upstream influence is at the confluence of the Pranhita and Godavari rivers. The Pranahita River is itself a confluence of various smaller tributaries including the Wardha, Painganga, and Wainganga rivers.

Hence option 1st is correct.
