Correct Answer:
C. Allama Iqbal
The correct answer is Allama Iqbal. The book Ilm-ul-Iqtisad (The Science of Economics) was written by Allama Muhammad Iqbal in 1903. It was one of the earliest books on economics written in Urdu and reflected Iqbal's deep understanding of economic principles and their application to Muslim societies. Quaid-e-Azam Muhammad Ali Jinnah was a lawyer and politician, not an author of economic texts. Sir Syed Ahmed Khan was a social reformer and educator, known for his writings on education and religion. Shibli Noumani was a historian and biographer. Therefore, Allama Iqbal is the correct author of Ilm-ul-Iqtisad.
