Match List-I with List-II and select the correct answer by using the codes given below the lists: List-I A) Ukai B) Patratu C) Pench D) Dabhol List-II 1) Jharkhand 2) Gujarat 3) Maharashtra 4) Madhya Pradesh

The correct answer is B.

Ukai is a multipurpose dam on the Tapi river in Gujarat (Surat district), built for irrigation, flood control and hydro power, so A matches 2. Patratu thermal power station is in Ramgarh district, which was part of Bihar until the 2000 reorganisation created Jharkhand, so B matches 1. Pench hydel project is in Madhya Pradesh, so C matches 4. Dabhol, in Ratnagiri district of Maharashtra, is the gas-based power project first developed with Enron, so D matches 3.

• Option A wrongly places Ukai in Madhya Pradesh and Dabhol in Gujarat.
• Option C wrongly places Ukai in Maharashtra and Patratu in Madhya Pradesh.
• Option D wrongly puts Ukai in Jharkhand and Pench in Maharashtra.

The concept is state-wise location of major dams and power plants, which recurs in the Indian Geography and Energy sections and in Mains questions on energy mix and inter-state projects.

Trap: Pench is a river that flows across Madhya Pradesh and Maharashtra, so students choose Maharashtra by default. Remember which state hosts the specific project, not just the river.
