Elimination through the publication timeline:
Instead of matching author by author, order the four works chronologically: Adam Smith's Wealth of Nations (1776) is the earliest, followed by Alfred Marshall's Principles of Economics (1890), then E.H. Chamberlin's Theory of Monopolistic Competition (1933), and finally J.M. Keynes' General Theory (1936) is the most recent among these.
If List-II is ordered by these same publication years, then (A) Wealth of Nations should pair with the earliest-listed item, (B) Principles of Economics with the next, (D) Monopolistic Competition with the third, and (C) General Theory with the last.
Cross-checking this ordering against the four options, only option (3), (A)-(II), (B)-(I), (C)-(IV), (D)-(III), is internally consistent with the chronological placement of each book.
Hence option (3) is correct.
