Match List I with List II and select the correct answer using the code given below the lists: List I (Dam) A. Hirakud B. Panchet C. Kosi D. Ukai List II (State) 1. Gujarat 2. Bihar 3. Odisha 4. Jharkhand
- (a)A-3 B-4 C-2 D-1
- (b)A-3 B-2 C-4 D-1
- (c)A-1 B-2 C-4 D-3
- (d)A-1 B-4 C-2 D-3
Correct — A, A-3, B-4, C-2, D-1. Hirakud Dam is on the Mahanadi in Odisha (A-3); Panchet Dam, part of the Damodar Valley project, is in Jharkhand (B-4); the Kosi project/barrage is in Bihar (C-2); and the Ukai Dam on the Tapi is in Gujarat (D-1). Only option (a) matches every dam to its correct state.
- (b)A-3 B-2 C-4 D-1 — It wrongly puts Panchet in Bihar and Kosi in Jharkhand; Panchet is in Jharkhand and the Kosi is in Bihar.
- (c)A-1 B-2 C-4 D-3 — It places Hirakud in Gujarat and Ukai in Odisha — both wrong; Hirakud is in Odisha and Ukai in Gujarat.
- (d)A-1 B-4 C-2 D-3 — It again places Hirakud in Gujarat and Ukai in Odisha, mismatching the two end pairs.
This is a standard 'dam to state' matching item. The reliable trick is to anchor each dam to the river it dams, which fixes the state: Hirakud on the Mahanadi (Odisha), Panchet on the Damodar (Jharkhand, a Damodar Valley Corporation dam), the Kosi barrage on the Kosi (Bihar), and Ukai on the Tapi (Gujarat).
Fixing even two dams confidently — say Hirakud in Odisha and Ukai in Gujarat — already rules out options (c) and (d). Then Panchet (Jharkhand) versus Kosi (Bihar) separates (a) from (b).
- Hirakud Dam — river Mahanadi, Odisha; one of the longest dams in the world.
- Panchet Dam — river Damodar, Jharkhand; a Damodar Valley Corporation project.
- Kosi barrage/project — river Kosi, Bihar (the 'Sorrow of Bihar').
- Ukai Dam — river Tapi, Gujarat.
- Mixing up the states of the DVC dams (Panchet is in Jharkhand).
- Placing Ukai outside Gujarat or Hirakud outside Odisha.
Asked as a dam-to-state matching set — anchor each dam through its river to fix the state.
Which one of the following pairs is not correctly matched? (Dam/Lake — River)
- (a) Govind Sagar : Satluj
- (b) Kolleru Lake : Krishna
- (c) Ukai Reservoir : Tapi
- (d) Wular Lake : Jhelum
Answer(b) Kolleru Lake : Krishna
Same dam-and-water-body matching skill, and it even shares the Ukai–Tapi pair used here. The trick is identical: anchor each dam/lake to its river.
Krishna Raja Sagara Dam/Reservoir is developed on
- (a) river Krishna
- (b) river Tungabhadra
- (c) river Godavari
- (d) river Kavery
Answer(d) river Kavery
The same dam-identification skill — linking a named dam to its river — which is exactly how you fix each dam's state in this matching question.

Hirakud Dam, one of the longest dams in the world, is built across which river?
- (a)Godavari
- (b)Mahanadi
- (c)Krishna
- (d)Narmada
Answer(b) Mahanadi — Hirakud Dam in Odisha is built across the Mahanadi.

The Ukai Dam is constructed on which one of the following rivers?
