Choose the correct answer from the options given below:

Correct option is B

A-IV, B-III, C-II, D-I is the correct match:
· Sartori (A-IV) is known for his contributions to democratic theory, particularly the concepts of Demo-Protect and Demo-Power, which refer to different types of democratic systems and their functioning.
· Morris (B-III) introduced the Physical Quality of Life Index (PQLI), a measure that assesses well-being based on literacy, infant mortality, and life expectancy, as a more comprehensive development indicator than economic metrics alone.
· Hayek (C-II) introduced the concept of Catallaxy, which refers to the spontaneous order that arises from individuals engaging in market exchanges, a key element of his critique of central planning.
· Popper (D-I) is famous for his philosophy of science, particularly the principle of Falsification, where scientific theories must be testable and disprovable to be valid.
