Step 1: Understanding the Question:
The question seeks to identify the dominant category of cargo that constitutes approximately 68% of the total cargo volume handled at Cochin Port.
Step 2: Key Concepts and Economic Geography of Kerala:
Cochin Port is one of the largest major ports in India, located strategically on the sea-route of the Arabian Sea and Indian Ocean.
The port has dedicated terminals, including the Kochi Refineries' crude import facilities and the International Container Transshipment Terminal (ICTT) at Vallarpadam.
Step 3: Detailed Explanation:
• Crude and POL: POL stands for Petroleum, Oil, and Lubricants.
The Kochi Refinery (BPCL-KR) located in Ambalamugal relies heavily on Cochin Port for importing raw crude oil and exporting refined petroleum products.
This steady, high-volume flow of oil products accounts for about 68% of the total cargo handled at the port annually.
• Other cargo categories: While the port handles timber, fertilizers, and coal, their individual shares in the total cargo volume are significantly lower compared to petroleum products.
Step 4: Final Answer:
The correct choice is crude and POL, which corresponds to Option (C).
