Model Answer

(D) All four are correctly matched.

All statements are accurate: Kandla replaced Karachi post-Partition; JNPT decongests Mumbai; Mormugao handles ~50% of iron ore exports; Haldia relieves Kolkata port.

Explanation

The textbook explicitly states all four facts: Kandla was developed after Partition due to loss of Karachi; JNPT was planned to decongest Mumbai; Mormugao accounts for about 50% of India's iron ore export; and Haldia was developed as a subsidiary port to relieve Kolkata. Examiners expect students to recall these specific details from the Major Sea Ports section.
