This question asks about a specific business collaboration between steel magnate Lakshmi Mittal and the Government of India, reported around 2007. The key is recalling which sector this partnership was actually in, since Mittal is popularly associated with steel, which can make people guess "Mining" by mistake.
Because the question is about a specific, named partnership with the Government of India rather than Mittal's general business interests, the correct match is the oil refinery project.
Let's summarize:
The correct answer is option (A), Oil Refinery.
