Question

Arrange the location of the following dams of India from North to South and choose the correct option:

I. Pravara    II. Salal
III. Koyna     IV. Gandhi Sagar

• A. II, IV, III, I
• B. II, IV, I, III
• C. III, II, IV, I
• D. III, IV, II, I

Hint:

Place each dam in its state first. Jammu and Kashmir, then Madhya Pradesh, then Maharashtra. Inside Maharashtra decide which of the two is nearer the north.

Answer 1

The Correct Option is B

Concept:

• With four options on the table, fixing only the first and the last dam is often enough to reach the answer without ordering the middle two carefully.
• The extremes here are the easiest to be sure about.

Step 1: Fix the northernmost dam.
Salal lies on the Chenab in Jammu and Kashmir, farther north than any other dam in the list. So item II must be first.
Options (C) and (D) begin with III and are rejected at once.

Step 2: Compare the two options left.
(A) reads II, IV, III, I and (B) reads II, IV, I, III. Both agree that Gandhi Sagar is second, so only the relative position of Pravara and Koyna decides the answer.

Step 3: Separate Pravara from Koyna within Maharashtra.
Pravara lies in the Ahmadnagar district in the northern part of the state, and Koyna lies in the Satara district further south, in the Western Ghats near Sahyadri.
Going from north to south, Pravara comes first and Koyna last.

Step 4: Pick the matching option.
Option (A) puts Koyna before Pravara, which reverses the correct order. Option (B) places Pravara before Koyna and fits.

Final Answer: (B) II, IV, I, III
