Step 1: Radiant City.
\n- Developed by Le Corbusier in the 1930s. \n- Characterized by high-rise cruciform towers, strict zoning, and extensive green belts. \n- Noted for its focus on vertical living. \n\[\nP \Rightarrow 3\n\] \n\n \n
Step 2: Conservative Surgery.
\n- Proposed by Patrick Geddes, recognized as the "father of modern town planning." \n- Advocated for urban improvement through selective demolition and renewal, rather than large-scale clearance. \n\[\nQ \Rightarrow 4\n\] \n\n \n
Step 3: Broadacre City.
\n- Conceptualized by Frank Lloyd Wright. \n- A low-density, decentralized urban model reliant on automobiles. \n- Each family was intended to possess at least one acre of land. \n\[\nR \Rightarrow 5\n\] \n\n \n
Step 4: Linear City.
\n- Introduced by Arturo Soria y Mata in Spain (1882). \n- The concept involves urban development along a single major transportation route. \n\[\nS \Rightarrow 2\n\] \n\n \n
Step 5: Final matching.
\nConsequently, the correct sequence is: \n\[\nP-3, \; Q-4, \; R-5, \; S-2\n\] \n\nThis corresponds to Option (B). \n\n \n
Final Answer: \n\[\n\boxed{\text{(B) P-3, Q-4, R-5, S-2}}\n\]
