The German politician who popularized the use of realpolitik was Otto von Bismarck. To arrive at this answer, you can eliminate the options one by one by understanding their roles and contributions.

Friedrich List was a German economist and a proponent of economic nationalism, but he did not specifically popularize realpolitik.

Wilhelm I was a significant figure in German history as the first German Emperor. While he played a role in the unification of Germany, he did not advocate for realpolitik.

Giuseppe Garibaldi was an Italian military general who played a crucial role in the unification of Italy. While he had political influence, he was not a German politician and did not popularize realpolitik.

Finally, Otto von Bismarck was a prominent statesman and politician in Germany during the 19th century. Bismarck is famously known for his implementation of realpolitik, a pragmatic approach to politics based on practical considerations rather than ideological or moral principles. Through his policies, Bismarck aimed to unify Germany under a Prussian-led and conservative rule. Therefore, the correct answer is option d, Otto von Bismarck.
