Concept:The correct order of the four sentences is determined by logical flow: start with the definition of dhoti, then its typical complement, then a historical reference, and finally Gandhi Ji's attire change.
Explanation:Sentence S defines the dhoti, which directly follows the introductory S1.
Sentence P mentions the loose tunic commonly worn with the dhoti, logically next.
Sentence R introduces Gandhi Ji’s preference for the dhoti, linking to the previous description.
Sentence Q concludes with Gandhi Ji abandoning western attire, leading smoothly into S6 about his shawl.
Thus, the correct sequence is S, P, R, Q.
Answer:C. S P R Q
