Concept:Arrange the jumbled sentences in a logical cause-and-effect sequence that leads from the challenge to the solution.
Explanation:Sentence R introduces the biggest challenge: reverse migration of urban migrants/poor.
Sentence S explains why migration happened – due to temporary shutdown of industries.
Sentence P describes where these migrants live to save on housing costs (slums, informal settlements).
Sentence Q states their need for decent, affordable rental housing near worksites, which directly connects to the action in S6 (ARHCs scheme).
Thus, the correct order is R → S → P → Q, i.e., RSPQ.
The other options disrupt the logical flow by placing the need before the problem or the description before the cause.
Answer:Option D (RSPQ)
