Step 1: Understanding the Question:
We are asked to identify the specific big project for which NRI industrialist Lakshmi Mittal partnered with the Government of India.
Step 2: Key Formula or Approach:
Separate Mittal's general known business, steel manufacturing, from the specific new venture referenced in the news at the time. The question is about a distinct partnership project, not his everyday steel operations.
Step 3: Detailed Explanation:
Lakshmi Mittal, chairman of what became ArcelorMittal, is globally known as a steel tycoon. Around 2007, his business interests broadened to include energy projects in India, and he entered discussions with the Government of India to help set up a large oil refinery, responding to the country's growing fuel demand and refining capacity needs. This was reported as a notable move beyond his traditional steel business. Atomic power and biotechnology have no link to his documented business dealings, so those options can be eliminated immediately. Mining is closely tied to his steel operations because steel needs iron ore, but the specific big government partnership asked about in this question is the oil refinery project, not a mining deal.
Step 4: Final Answer:
The project for which Lakshmi Mittal partnered with the Government of India is the oil refinery project, option (A).
