Explanation:

• For the first question: Adam Smith, in The Wealth of Nations, emphasized the role of self - interest in a free market economy (the "invisible hand" concept). A centrally planned economy (A) and government - controlled market (D) go against his free - market ideas. A mixed economic system (C) is a combination that came later, while Smith's focus was on the free market.
• For the second question: Joseph Lister is known for introducing antiseptic surgical procedures. The microscope was invented earlier (A). Vaccination development is more associated with Edward Jenner (C), and blood type classification with Karl Landsteiner (D).
• For the third question: Louis Pasteur is famous for the pasteurization process. Blood transfusion methods (A) were developed by others. Antiseptics (B) were more Lister's contribution. Surgical techniques (D) were not his main focus.

Answer:

1. B. A free market economy driven by self - interest
2. B. Antiseptic surgical procedures
3. C. Pasteurization process
