The correct answer is option 2: I-B, II-C, III-A, IV-D. This means:

I. Amartya Sen is matched with B (The Argumentative India). This is correct as Amartya Sen wrote `The Argumentative India.`

II. Bimal Jalan is matched with C (The Future of India). Bimal Jalan is indeed the author of `The Future of India.`

III. Arundhati Roy is matched with A (An Ordinary Person’s Guide to Empire). This is also correct as Arundhati Roy is the author of `An Ordinary Person’s Guide to Empire.`

IV. Mani Shankar Aiyar is matched with D (Confessions of a Secular Fundamentalist). Mani Shankar Aiyar wrote `Confessions of a Secular Fundamentalist.`

The other options do not make the appropriate matches between authors and their respective book titles, which is why they are incorrect.
